Ok,I'm back.
Got it hooked up finally and speedo,tach,and all gauges work except for the volt meter and I haven't verified the fuel gage yet.
I didn't use the BCM so I have a few warning lights(diodes) to contend with.
I don't know if I have to connect something else to make the volt meter work or if the servo motor is bad.
Does anyone know how to check them?
tell us how you made it work! i want to know
1985 Silverado LQ4/4l80e Turbonetics Single Turbo, 60lbs injectors, air to water intercooler, PST driveshaft, ARP head & rod fasteners, Custom cam, HP Tuners, PLX wideband, DUAL tanks still work!
I'll give you the easy version.
I connected the ipc harness wires as follows;
pin A1 mil to pin g on c100
pin A4 vss to pin d c100
pin A5 tach to pin k c100
pin A6 class 2 to pin h c100
pin A8 rt turn sig to right turn signal in harness
pin A11 panel light to panel light in harness
pin A12 ground to ground
pin B1 left turn sig to left turn signal in harness
pin B9 ign voltage to ign voltage
pin B11 bat voltage to bat voltage
pin B12 ground to ground
That's how I did it,however I do have a few warning lights(abs,airbag,brake,etc.) to get around yet.
The odometer(with correct milage for the engine),shifter display, and even the cruise lights up when its on.
I have it installed in the dash temporarily til I figure out how I want it to look.
I'll try to post a pic this weekend.
I'm going to replace the stepper motors for the gas and volt gauges when I get the chance to make sure they are ok.
