heated O2 sensor questions
I have a 92 coupe and its sensors are not heated , and i need heated O2 sensors, so , I called t.p.s and they have a 3 wire one for 60$ a piece, so I called a local parts store for 94 heated ones, and they had them for 40$ a piece, but a friend of mine can get them free, my question is will they work and if so how do I wire them, what wires go where, which is signal, which one is a 12volt source, and which 2 are grounds, thanks any one who can tell me.. :chevy :crazy: :chevy

Gogo,
Hey there are several posts going on right now on the same subject, please read!
I will tell you there are 3 wires:
1. The odd colored one is the sending wire which hooks up to to existing wiring.
2. There are 2 others that are the same color. These are the 12 v source (only when key is on) and the other is ground. Does not matter which one you use for these two.
the rest can be found in other threads. I actually have one. Do a search on my name.
Good luck. Be sure not to put the sensor any farther back than the collector if your moving it!
