LQ4 PCM on LS1 harness This may be a poor question, but I noticed the basics on the pin outs were close to the same from the truck and ls1 RED/BLUE harness besides the A/c and maybe fuel gaues. I know I should buy a bench harness but i just wanna flash the truck ECM. I know this is not wise but was wondering if anyone has tried it.
