PCM pinout for 2002 Topkick/Kodiak/Isuzu truck with 8.1L engine

[dzidaV8]

Hi!

Just as in the title, does anyoune have wiring or pinouts for 01-02 Topkick/Kodiak/Isuzu truck with 8.1L engine?

[kur4o]

It is the medium duty line of chevy trucks and is hard to score a diagram. I will try some other source too.
At least I found info for the PCM

MODULE, PWRT CONT (DMNP, DJZX, DLAC) (ACDelco #12200411) (REQUIRES PROGRAMMING)

If you have a valid vin I will try to get a bin file.

This is for Chevy C-Series Medium Duty Truck B7
