dis in a 94 cutty

[toastemcutlass]

so i went to the junk yard today and found one dis in a 90 cutty...i want to wire it in but am not sure what wires go where... there doesnt seem to be the harness so im going to have to run wires... the black plug has a black, purple, green adn orange wire and the blue has orange pink/black, yellow, gray and two blacks and a blue wire.. if any one could help i would be so greatful

[jeremy]

dis?

This is a copy of one of the emails i got from somebody from this message board long time ago and it helped me.

The BLUE connector is C1.


Wire A = a RED wire. Connect it to an ORANGE wire that
is HOT ALL OF THE TIME. (I connected mine to the
ORANGE wire that gives power to the cigarette lighter,
but it is recommended that you connect it to the ELEC.
Fuse #2 constant +12V (top row, middle fuse).)


Wire B = PINK/BLACK. Connect it to a wire that is HOT
IN RUN. (I connected mine to one of the PINK/BLACK
wire in my dash, but it is recommended that you
connect it to CLUST. Fuse #9 switched +12V (3rd row,
far right).)


Wire C = BROWN. Connect it to the light on input. In
my car I have a YELLOW wire in slot C10 but I think
that that is exclusive to the digi-dash. I want to soy
that there should be a YELLOW wire coming out of the
headlight switch that should work. I know that on my
dash, when the lights are on, and the display is at
MAX, then it has no power in the wire, but when I
adjust the lever down, the wire becomes hot, and dims
steadily. I use a tester that is just a screwdriver
looking thing that has a point at one end, and an
alligator clip that you hook up to ground.


Wire D = GREY. Connect this to one of the grey wire
for illumination. I hooked mine up to the GREY wire
that lights up the bulb for the cigarette lighter
light.


Wire E = BLACK/WHITE. This is a ground.


Wire F = BLACK/GREY. This wire is not used.

Wire G = YELLOW. Connect this wire to the LITE BLUE
wire in the dash (You may not have this wire). This is
your English/metric wire. In my car, I push a button
on the dash to change it from English (MPH) to metric
(KPH). When this wire is hooked up, it automatically
changes the DIC display from one to the other when the
E/M button is pushed on the dash. This is a wire that
is not necessary for the DIC to function, so if you do
not have the wire, then just leave it unconnected.


Wire H = BLACK. This is a ground. I hooked this up to
the BLACK wire connected to the cigarette lighter
light.



The BLACK connector is C2.


Wire A is ORANGE. Connect this to the ORANGE wire
coming out of the ALDL connector under your dash. This
is your SERIAL DATA INPUT where the DIC will get the
info for your gauges button.


Wire B = DARK GREEN. Connect this to the DARK GREEN
wire in the dash. This is your Vehicle Speed Input. In
my car it is wire number D15.


Wire C = PINK. Connect this one to the PURPLE wire in
the dash. This is your vehicle Fuel sender wire. In my
car it is wire number D13.


Wire D = BLACK/GREEN. This is another GROUND. It is
not used in the 91 model.



Driver Info System was not available 92+.


You will not find a new cutlass with one. If you put
one in your car, then it will go where the storage
cubbyhole is under the ashtray. The screw-holes for
the 98 Regency’s DIC is identical the Cutlasses, so it
will go there with no problem. If you get the DIC out
of a Cutlass, then be sure to get the storage pocket
as well. IF (OR WHEN) you get the HUD, then the
control switch will go where the storage is. 89-90
cars got a little pocket in the empty space. HUD
control panel was mounted above the headlight switch
(below the dash pad).
91 cars got a little pocket if they didn't have HUD.
Cars with HUD got the control panel instead of the
pocket.



Is your headlight switch up high next to the
speedometer with the foglight switch next to the air
vent? If so, then the HUD switch goes in the pocket.
My car headlight switch is located next to the vent,
with the foglight switch next to the speedo. (INT'L
models also had the BASS BOOST switch as well as the
foglight switch) But I will still put the HUD switch
next to the DIC.

[Robby1870]

Does anyone have one of the above description for a GP DIC?

[toastemcutlass]

norbi your the best..i figured how to give it power, the lights and the diming but i had no idea about the gauges stuff...youve been a big help :D

[TeeJay3800]

dis?

Thats what I think when people use DIC. My CS says Driver Information System. Not Center. Apparently GPs say DIC.

[GnatGoSplat]

None of the fuel economy stuff will work in a 94 though. :(

[jeremy]

Thats what I think when people use DIC. My CS says Driver Information System. Not Center. Apparently GPs say DIC.

I learn something new everyday

[toastemcutlass]

so you say the fuel econ wont work? do you know what does of the fuel stuff....i hooked up the fuel sending unit wire and it tells me a range..not sure if its right..but it doesnt tell me how many gallons i have..is that right?

also how does the oil life thing work..i wouldnt go by it but are you able to reset it or how does that work?


thanks again as always im sure you guys will know

[GnatGoSplat]

Yep, that's right, the fuel econ stuff won't work. I don't think the range info is accurate either. The DIS gets fuel info from the ALDL serial data. The ECM is constantly sending data on the ALDL, called "chatter". Within this chatter, there are 2 bytes that contain fuel consumption data sent by the ECM. I think it calculates that based on injector flow rate and pulse width. Anyway, on 88-93 cars, the values are accurate. On a 94-95 3.4 DOHC, those values are a fixed number that never change. That's why the fuel stuff won't work. It should be possible to modify the code in the MEMCAL to spit out the appropriate fuel data where it needs it, but I don't know how to do it.

Yeah, you can reset the oil life thing. I think you press OIL and RESET at the same time for a few seconds until you see the oil life go to 100%. It calculates oil life based on engine RPM and coolant temp. GM's formula is actually pretty good, I used it religiously on my 89 and that car is up to 198,000 miles with perfect compression. It's nice, I never have to remember to change the oil because the car will tell me to do it when it's ready.

[joey b]

if I have a 92 without the DIS, how hard is it to hook up? Are all of the wires right there for it?

[GnatGoSplat]

It's not that hard. All the wires you need to tap/splice into are in the main wire harness that goes up into the dash and behind the radio. I don't know if your car would be prewired for it or not, but that would be the first thing to check. If your car is prewired, I think the connectors would be taped up around the climate control harness.

[phantomshado]

I have a 94 with a DIC, the GP variety. I don't have the 3.4L dohc, I am stuck (currently) with the 3100. Will the DIC range stuff work with that since its just a 3100??? Thanks, and yeah, does anyone have the wiring info specific to the DIC, or is it the same for the DIS? (BTW, I have the weird LCD one, like the kind in TGP's)

[GnatGoSplat]

No, it's less likely to work on a 3100 car because the 3100's used the next generation PCM which was ODB-II compliant.

[PaPaPooh]

No, it's less likely to work on a 3100 car because the 3100's used the next generation PCM which was ODB-II compliant.

my 89 prewired for one?

[GnatGoSplat]

Probably not, but it doesn't hurt to check. I've seen 90+ that are prewired, but not 88-89.

[Rossp]

This is going to sound awfully ignorant but what does a DIC do? and where on my car would it go?

[GnatGoSplat]

It's a little computer. Has a clock and calendar function. Says "GOOD MORNING", "GOOD AFTERNOON", and "GOOD EVENING" on its little display depending on time of day. It can display fuel economy information: Range (distance to empty), Average Fuel Economy, Instant Fuel Economy, and gallons used. It has a digital "GAGES" function, showing numerically the tach, volts, and coolant temp. It has Trip Computer functions where you enter number of miles to your destination, and it will calculate the ETA and miles remaining. Lastly, it has an Oil Life Monitor and will tell you when it's time to change the oil.

[Rossp]

So where on my dash does this little gadget fit?

[Baddflash]

It seems that there are some differences with the GP DIC, I don't know if it matters but mine is out of an '90 STE. It has to do with the lighting.

First, A3 (brown) is said to turn on the lights for the DIC, where the cutty uses grey.

2nd, A5(grey/blk) dimmer control SW "E", B3(Grey) Dimmer control SW"F"

The cutty used brown for it's dimmer control. Do I have to use both? Is there 2 different inputs cause there's two areas to control? Could I wire them together?

To guess I would say A3 would turn the lights on and B3 would be for the dimmer control. But I'd like to know for sure.

Assuming that's true I was going to wire as follows.

A1-orange- Constant 12v
A2-pnk/blk- Keyed source 12v
A3-brown- Lights on (panel)
A6-dk grn- VSS (speedo)
A7-orange-ALDL input (orange wire)
A8-black-ground
B3-grey-dimmer control (maybe both A5 & B3 together.)
B6-purple-fuel sender
B8-black-ground

Would appreciate any help, now that it's installed I need to get it working.

[Anonymous]

Ive done the DIC install into a GP, which I think is similar. I put the nice 88-93 unit into a 95. It took about half an hour to splice everything in... PM me for details.

[Psych0matt]

any pics of the dis installed? (in the 94)

[rudefyet]

That'd be interesting to see pics of :wink:

pics please....I want to put on in my '97 Cutty, custom fit to where the radio currently is, then of course relocate the radio......does anyone have any idea if a DIC can be wired into a 95-97 Cutty correctly??

[Psych0matt]

HELP!
I'm having trouble with my DIS
I did find this harness though, is that anything? or do i have to splice everything? ( i started to but couldn't get power other than a few blips on the screen)
http://websites.anderson.edu/~mdsteenbergh/plug.jpg

[GnatGoSplat]

That harness you found is for the HUD controller.

Yes, you do have to splice everything to put DIS in a 94 Cutlass.

[Psych0matt]

hmmm :-/ so i have to splice for the dis
but not for a hud? :-D

[GnatGoSplat]

Yep, that's right, because HUD was an option, but DIS was not.

[dsgrntld187]

Oh shit where did you find that harness? I'd rather have HUD than DIS..

Would this HUD work for my car?

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33678&item=7905942647&rd=1

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33678&item=7905942647&rd=1

No.
Well, I guess you could make it work, but easier to use a Cutlass HUD.

[dsgrntld187]

Would it just be plug and play or would it need rewiring? I don't mind the gaping hole in the dash part, just the rewiring part.

[GnatGoSplat]

It's been awhile since I had a Bonneville HUD in front of me, but it would require rewiring and dash modification. The Bonneville HUD is HUGE and differently shaped. I seem to recall it had different connectors too.
I would get a Cutlass HUD, it's plug & play.

[dsgrntld187]

Does anyone have one they would sell or uh.. "donate" to charity? :lol:

[Psych0matt]

While we're on that, I want one too now that i don't have as much modifying to do it :-) (i guess ill check ebay and the for sale section)

[Psych0matt]

Ok, so I have mine all powered up and everything, but still cant figure out where the three data wires go to. It says the aldl connector. What is that? and do all three go to that? thanks a bunch

[GutlessSupreme]

Are you talking HUD or DIS?

I don't know what's done in '94+ cars, but as said in this topic..

DIS:


The BLACK connector is C2.

Wire A is ORANGE. Connect this to the ORANGE wire
coming out of the ALDL connector under your dash. This
is your SERIAL DATA INPUT where the DIC will get the
info for your gauges button.

Wire B = DARK GREEN. Connect this to the DARK GREEN
wire in the dash. This is your Vehicle Speed Input. In
my car it is wire number D15.

Wire C = PINK. Connect this one to the PURPLE wire in
the dash. This is your vehicle Fuel sender wire. In my
car it is wire number D13.

Wire D = BLACK/GREEN. This is another GROUND. It is
not used in the 91 model.

I orange wire (wire a) is the only one going to the ALDL connector. it should be a plug right in the driver foot well, next to where the console ends.

Wire B and C get wired to wires in your cluster's harness.

and then of course black/gr is a ground

[Psych0matt]

I got the DIS all installed and everything, and I knew that the fuel econ stuff wouldn't work, but is the trip info and stuff supposed to be able to? if anyone knows please let me know how

[GnatGoSplat]

I'm pretty sure that's supposed to work too.

[Psych0matt]

any help with my last post? just thought id bump it :-)

Id like to get at least the trip info working, as well as the fuel econ (with some wiring probably)

Thank you i finally found the pinouts i have been searching so hard for. :mrgreen:

[Psych0matt]

ah ha, glad to see you found it. I remember this thread from back in the day :lol:

[rockfangd]

this was the only post that did not have an expired webpage. Waht has to be done t make all of the features operational on a 94 cutty

[Psych0matt]

wire that all in as such, and then buy/make a chip

[rockfangd]

where can i get a chip and where does the chip go. I want 1

[Psych0matt]

Shawn (Gnatgosplat) did mine, he might be able to do you one

[rockfangd]

I PM him. My question is where does the chip go. Am i going to have to mail something to him so he can do work or do i just put it in somewheres lol. I feel dumb lol :redface: :question: :question:

[Psych0matt]

it depends on what he has. The one I bought from him was a reprogrammed chip from something else, he just redid it. If I remember right, you can either have a chip reprogrammed, or mine is an add on, basically using my stock chip still, just with another chip in between. All you have to do is get to your computer box and take out the screws, and then pop out the chip, and replace or add the new one, depending on what you get

[rockfangd]

he states that he does not have one for 3100 all he has is 3.4

[Psych0matt]

youre probably out of luck then for fuel econ. i forgot that on top of the 94 computer you also have to compensate for engine size. so yeah, dont think anyone's figured out the 94 3.1 rate :sad:

[rockfangd]

well all i really want to get by aprilis the Hud unit and switch 2nd gen. (FRom jeremy) and the DIS pigtails from crazy k. I cannot find a set in salvage yards. What other cars can i look for the DIS pigtails in, (if there is any other with the blue and black pigtails)? i will just have to worry about the econ after everything is complete

[Psych0matt]

earlier cuttys are the ones to look for the pigtails, but usually if there isnt a DIS still in the car, the pigtails were taken too.

[rockfangd]

yeah as far as i know the ones that have them are 89-92 coupe or sedan, sport pod or no sport pod. I am just hoping crazy k finds one for me :gr_grin:

[rockfangd]

really. checkin it out :biggrin:

[Crazy K]

I paid $18 for one from a yard in sunday. :P

I wonder if the obdII system could be made to work with the DIS? I have a different reason for wanting to do OBDII as well.

[GnatGoSplat]

I wonder if the obdII system could be made to work with the DIS? I have a different reason for wanting to do OBDII as well.


It most definitely could. The OBD-II PCM's have a UART output which is compatible as far as signal levels.
You'd just need to reverse engineer the code in the flash memory and write some routines to spit out correct code on the UART!

well since I have yet to delve into the world of hacking or re-programming obdII where should i start?

[GnatGoSplat]

First think I think you'll need to get a dump of what's in the flash memory and also find out what kind of CPU is in it in order to make a disassembled listing of the code.

[rockfangd]

so basically is there a way to make thesefeatures operational on my 94 cutty 3100, or am i out of luck

[94CutlassSLCoupe]

No fuel economy on a 94 3100. In the car i sold to jay, everything worked with the exception of the fuel data. You just have to run all the connections with the exception of the speed to the ALDL data connection on the diagnostic connector. The computer does not send fuel data at all

[rockfangd]

well dont i still have to connect the aldl wire anyhow, doesnt it do other things. I thought maybe the DIS told temps and tach also

[94CutlassSLCoupe]

yes, it tells the coolant temp and also the tach...that comes from the ALDL stream

[rockfangd]

so how difficult would you say the job was. All of the wires were easy to run?

[Psych0matt]

its splicing a few wires, 2 feet at the very most (and thats very generous), and mounting it in, which is just some screws. I'd say it's maybe 4 out of 10, 5 out of 10 if you dont pay attention to things when youre doing them :lol:

[rockfangd]

I am shocked because i just saw a band new DIS on ebay. in the box. :mrgreen: they have a reserve on it hmmm i wonder what it could be

[Psych0matt]

huh, i couldnt find it

[rockfangd]

I found it by doing a search for oldsmobile. then 1988 to 1993 oldsmobile cutlass. and newly listed. i think it was like pg.5 of 7. very nice

[Psych0matt]

hmmm, is anyone else thinking of getting that? if not, I might try for it. keep it out of the AW section for now perhaps?

[rockfangd]

I was quite surprised when i found that. I am very curious on what the reserve is

[Psych0matt]

oh, didnt realize there was a reserve. nevermind, i wont bother

[rockfangd]

lol. me either. i am going to ask but even if i do it is gonna go for alot

[rockfangd]

BUMP! Can anyone tell me if there is an easy way to add ECC into my 94 cutty. there is a 1993 in my local yard with it and i might chance it. Can i swap the whole entire unit. and where do all of the wires come from. ??? so many questions lol

[Crazy K]

adding ecc can be done. there's a write-up....

here you go!
http://www.wbodysource.com/modules.php?op=modload&name=News&file=article&sid=20&mode=thread&order=0&thold=0

[rockfangd]

thanks,

[rockfangd]

is there any easier way, like maybe trading the whole hvac unit, if that is even possible, also foes anyone know if i switched the modules if i would still hav to rewire the whole ecc. i really like the feature but it seems way tocomplicated for it to be worth my while. i would rather switch the whole thing lol

[GnatGoSplat]

There is no easier way.

[rockfangd]

Trading the car for a Cutlass with ECC?

I'm a smart ass, I know.

lol yeah well i can be quite the pita lol

[rockfangd]

i cant believe i placed a 76.00 dollar bid on that dis, the reserve was 75. i lost it by 1.00. i tried but i wasnt home to place the last bid

[rockfangd]

Well i finally installed my sport pod and my DIS and couldnt be happier. I really like how it has a specific readout. i only have a few questions. what does low feul range mean? it comes on after the greeting wth a loud beep. also if someone could tell me if the oil life reset works with my 94, and how do i reset the oil? I may have a few more tomorrow and i will post pics tomorrow. The only thing that i really do not care for is the ashtray in the pod. i do not smoke so i will never use it but it looks very tacky :surprised: lol

[Psych0matt]

fuel range is how far you can drive on the gas you have in the tank, itll always say low range or something since you have a 94/3100

[rockfangd]

what about fuel level percent. when i check it it says 00. what i am basically asking is what does the fuel wire actually do. It is the green wire i believe?

[Psych0matt]

i dont think anything fuel related works :sad: That's OBD 1.5 for ya

[rockfangd]

well one thing i did notice is the the average mph is almost like watching my speedometer lol. I am still going to post pics but it is so cold :question: :rolleyes:

[Psych0matt]

yeah, the average will do that for a while until it's on for a while. I like hitting the reset button over and over while speeding up and watching it :lol:

[rockfangd]

so does that feature actually work then.

[Psych0matt]

it should, did on mine

[rockfangd]

i wish that the feul usage worked. all it ever says is 0.0 gals. Also if someone knows when i hooked the wire up for the parking lights. when i switch the parking light switch on the display goes out but my ub3 dims normally. when i shut the parking lights off the display comes back on. What could i have done wrong?

[Starflare5]

I know this is a really old thread, but, I connected most of the wires of my DIC to the only component that made any sense, the dashboard.. including the VSS and fuel guage wire... Now I need that chip modification to get the data I/O to work correctly. here's an important note about the DIC, there are 2 grounds. One is a general ground and the other is a guage ground... Primarily meant for the fuel guage since most other functions are part of the serial data stream. If you have this ground connected to the guage ground in the dash, the fuel econ should read properly and even in a '94 cutty after the serial data I/O mod . Why would this affect the fuel reading? Here's a tip: you're fuel float is actually a variable resistor in the fuel tank with the guage wire at top and the guage ground at bottom. The closer this resistor's contact gets to the fuel guage wire (float arm goes down, contact slider goes up), the less fuel you have. The closer this slider gets to the guage ground, the more fuel you have. Both the guage and DIC are designed to reflect just that read out. Was thinking that this might help a few of you that are getting 0.0 on fuel usage. The guage ground is the black wire in the small black plug of the DIC. Do not combine this ground with the standard ground of the blue conector, and, in some cases, you may even leave the guage ground disconnected completely.

I hope this helps,
Starflare5.
