I need to know which O2 harness is for the front, and which is for the rear. Right now I have the front O2 Sensor hooked into the harness coming off of the harness that the thermostat sensor is on, and idi harness, etc. There is another one that the VSS and reverse sensor is on, which one is the proper one...
Sorry about the dumb question, trying to straighten out all the wiring
I take it no one knows?
In the haynes manual it only shows the oxygen sensor harness from the older years and not for my Ecotec
