O2 sensor wiring
O2 sensor wiring I have Corvette manifolds that came with O2 sensors that have a flat 4 connector. I want to change the connectors on the harness to match the flat 4. http://198.208.187.182/internet/Part...cpartnbr=PT368 The harness has ppl, tan ,pink and green on one side. The other side has ppl/wht, tan, pink and b/wht. The sensors have ppl, tan, br and br.
I already know how to match the ppl and tan wires. Am I correct that these are heated sensors and that the br wires are for that circuit? If so does it matter which one goes to the pink and which one goes to the green?
Would I be able to do a continuity check from the pins in the connectors to the PCM plug to determine pin outs for these wires?
Thanks for the help,
Bob

Yes, the brown and brown are the heater wires and the polarity doesn't matter. Just put the browns where the pink and black was and it'll be fine.

Great guys to deal with and they know their stuff. I think I saw the connector listed in their store but give them a call to confirm it is the correct part.
