I want to make a Bench Harness for the PCM in my 2000 truck. I need a wiring diagram to make sure that I'm doing it correctly. I assume that I will need the following:
PCM connector and wiring (Salvage Yard)
Sub D style connector to Flashscan (Radio Shack)
Ignition Switch (Radio Shack)
Fuse (Radio Shack)
Alligator clips (Radio Shack)

I've done some searching but I cant find the interconnect/interface, but I know that I've seen one before. Does anyone have this? I have my factory manual and I'm sure that I can develop it myself, I'm just trying to save some time.

Thanks,

You're looking for the DLC connector? or just a pinout? Here's some info I found quickly... If it's something else lemme know and I'll see what else I can dig up

Part 31 in this diagram , 12110250, looks like it goes for just over a buck ... assuming that's the connector (black piece)

THen


2= J1850 Bus+
4 = chassis ground
5 = signal ground
16 = Battery power


Is the Pinout

I don't know what the DLC stands for. I want a wiring diagram. I assume that I need power, ground, data, and switched ignition power.

DLC Data Link Connector, the Connector the cable plugs into , sounds like the same as the Sub D style connector you mentioned

Or do you mean the pinouts on the PCM to power the PCM up?


The pic I have above w/the 16 pins is the piece the flashscan cable would plug into inside the vehicle and provides the pinouts for a GM OBDII vehicle

If no one can provide a definitive answer, may want to contact the guys at www.speartech.com also , they make a harnass for bench testing PCMs, so they can probably provide a definitive answer for your project
