Hey fellas I got some issues maybe you all can help me solve. I been building a 77 crew cab chevy and installed a 97 12v and I've been working on the dodge harness and pcm to fit in the truck because I live in California the ref wants a working obd2 system so I've been busy chopping up the harness to work. I just have pcm and engine harness. I got most of it done and rigged up a obd2 port and got a couple codes pulled witch don't look good p1492 and p1389 the altinator is not charging and the grid heater never cycles I'm not sure if I'm missing something in the harness or if the pcm is toast. What do you guys think?
