The Oldsmobile Connection

[rhempton]

Hello,

I am trying to find a wiring diagram for the Driver Information System from a 1989 cutlass supreme international. There are two connectors, one is a 4 pin and the other is an 8 pin.

Does anyone know if the factory service manuals would have a detailed diagram? I would like to find out before I order one.

Any help would be greatly appreciated.

yes, the factory service manual has the diagrams you need. there is also a write up on the internet that i followed when i put a DIS in my 88 cutlass supreme.

Do you have a URL for that write-up on the internet? I searched but couldn't find anything.

Would anybody that has a service manual be willing to provide a diagram or schedule of the connections? I know which wires power the unit but am not sure about the data connections.

Thank you very much man! You are awesome! 8-) Some good information on that link. Posted here for future reference:

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.
