6th Gen ('00-'05): GMTech2 Tips for usage
Ive been looking at the bench harnesses. Considering building my own.
Do you know if the LS1 Delphi blue Bench harness will work on our 3800 PCMs?
Im trying to find a good wiring diagram to make my own, but Im getting conflicting information
Also, I'm getting a second PCM to do all my bench testing on. Im not ready to full commit to the factory PCM.
Do you know if both PCMs are programmed to my VIN can I interchange them with out relearns? Or am I gonna need to relearn the PCM everytime I put one in

Follow up for anyone interested.
The LS1 PCM Bench Harnesses will work with our PCMS. The only thing you may need to double check is pin 58/59 for Class 2 Serial. This Pin seems to be interchangeable depending on the era for PCM.
Hope someone finds this helpful.
