O2 signal wire?
I have a 2002 civic and i need to hook up my air/fuel gauge but i dont know which wire is the signal wire. There are 4 different color wires after the connector. There is a green, gray, and two blacks with stripe. Which is the signal wire? HELP ME PLEASE....

Re: O2 signal wire? (NO2CIVIC)
Yea you will want to run it off the signal line.. white wire most of the time but i guess in ur case it changes but that's fine.. I like to run them directly off pigtail a few inches up from the plugs, just cuz i like it to look clean.. Sorry i don't have pinouts for the 02 civics but you can trace the wire if your really want to tap it in by the ECU. Just use a voltmeter with a continuity tester.. Have fun
