2002 lancer oz o2 sensor signal wire?
hey im about to put an air fuel gauge in but I don't know which wire on my o2 sensor is the signal wire. I have a blue wire, a white wire, and 2 black wires to choose from, I think it is the blue wire, but not sure, i want to be sure, before I hook up my air fuel gauge and break it or something else.

You need to tap the White wire at the ECU for a narrowband a/f. Check out the thread in the HOW TO section for installing an SAFC. It gives you the ECU diagrams for MT and AT. If i remember correctly it was like the plug all the way to the right, 5th pin from the left on the top.....Check out the install thread
