NORBI Posted January 7, 2004 Report Share Posted January 7, 2004 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. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted January 7, 2004 Report Share Posted January 7, 2004 Does anyone have one of the above description for a GP DIC? Quote Link to comment Share on other sites More sharing options...
toastemcutlass Posted January 8, 2004 Author Report Share Posted January 8, 2004 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 Quote Link to comment Share on other sites More sharing options...
TeeJay3800 Posted January 8, 2004 Report Share Posted January 8, 2004 dis? Thats what I think when people use DIC. My CS says Driver Information System. Not Center. Apparently GPs say DIC. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted January 8, 2004 Report Share Posted January 8, 2004 None of the fuel economy stuff will work in a 94 though. Quote Link to comment Share on other sites More sharing options...

toastemcutlass Posted January 9, 2004 Author Report Share Posted January 9, 2004 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 Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted January 9, 2004 Report Share Posted January 9, 2004 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. Quote Link to comment Share on other sites More sharing options...
joey b Posted January 9, 2004 Report Share Posted January 9, 2004 if I have a 92 without the DIS, how hard is it to hook up? Are all of the wires right there for it? Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted January 9, 2004 Report Share Posted January 9, 2004 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. Quote Link to comment Share on other sites More sharing options...
phantomshado Posted January 14, 2004 Report Share Posted January 14, 2004 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) Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted January 14, 2004 Report Share Posted January 14, 2004 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. Quote Link to comment Share on other sites More sharing options...

GnatGoSplat Posted January 15, 2004 Report Share Posted January 15, 2004 Probably not, but it doesn't hurt to check. I've seen 90+ that are prewired, but not 88-89. Quote Link to comment Share on other sites More sharing options...
Rossp Posted January 22, 2004 Report Share Posted January 22, 2004 This is going to sound awfully ignorant but what does a DIC do? and where on my car would it go? Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted January 22, 2004 Report Share Posted January 22, 2004 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. Quote Link to comment Share on other sites More sharing options...
Rossp Posted January 22, 2004 Report Share Posted January 22, 2004 So where on my dash does this little gadget fit? Quote Link to comment Share on other sites More sharing options...
Baddflash Posted May 28, 2004 Report Share Posted May 28, 2004 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. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted May 29, 2004 Report Share Posted May 29, 2004 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. Quote Link to comment Share on other sites More sharing options...

That'd be interesting to see pics of 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??
