I've looked through numerous forums on here and still cannot find what i need. Its fairly simple i think. I just need to know which wire on the ECM wiring harness or going to the ECM is the oxygen signal (+) wire. I have a '94 Accord EX Coupe.

Its a sunpro gauge like you can get at autozone or wal-mart and its not the fanciest but i just want a good idea of my air/fuel mix. I already have the power, ground, illumantion. all that is fine. i just want to know which wire. I don't want to run the wire to the oxygen sensor because that just seems more work than i really need to do. So if anyone knows what color of wire and where about on teh harness its located please let me know. I really don't want to have to jack the car up and crawl under and find it.
