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.

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

[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.

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.

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.
