I am completing my own custom OBD2 > OBD1 conversion harness. This is my daily driver. I have checked, rechecked and triple checked things, but of course I am still concerned. If something is wired wrong, what the worse that can happen? I mean I am thinking the ecu will be fried which I can live with, but I don't want to like short out my whole car or something. What do you guys think would likely happen if something is wired wrong? Which connections should I check yet again to prevent catastrophe from striking?
TIA
