My money is on the harness at this point. I took a quick look at the wiring and it looks off. I don't know by how much but the wires are definitely in the right place. I just want to fix the harness since I have it all right here and I paid good money for it. I found the OBD1 pinout on hybridgarage.com but I am still lacking the OBD2a pinout. :thinking:
