Can I run a 1 wire 02 sensor w/ the obd0 PR4 ecu? if I can.. where do I put that 1 black wire. When I had the car started back in the day, it idled high, and the check engine light was on. i'm pretty sure it's because I didn't have the 02 sensor wired up correctly. I tried googling this topic but people don't know ----. Thanks guys

 

obdo=1 wire on all cars



o2 wire plugs into the harness it will be a one wire circle plug harness side will be on the dist side of the harness

 

Thanks Chris.. also I put that clutch on today. The discs are definatley different. The 92-93 looks alot more high tech, but oh well the one you sold me is surely better anyway.. btw I have a 91' LS trans on the way from Rhode Island.. got a killer deal.. 200 bucks from King Auto Parts
