Air/Fuel Ratio Gauge Install help PLZ
I just got an Pro-comp ultra-lite air/fuel ratio gauge today and was reading the instructions....My 98 ex's oxygen sensor is apparently a heated one since it's got 4 wires (a green, a white, and two black wires)?? My question is does anyone know which one of these wires is the signal wire?? If not can someone point me to an online source that shows the wiring diagrams for my car?? thanks...

Rep Power: 0 That doesn't help me at all...I've got the factory instructions but I need to know which wire on the oxygen sensor itself is the signal wire to the ecu and which one is the signal wire for the sensor heater....

Rep Power: 0 I figured I might have to travel to the dealer for the answer but was hoping I could find someone on here that's installed an air/fuel ratio gauge themselves with a 4 wire oxygen sensor [IMG]i/expressions/face-icon-small-tongue.gif[/IMG] Oh well, thanks for the responses man, appreciated.

Rep Power: 0 would it matter (or burn something up) if I turned on the car and hooked the gauge to the battery then tested it in the white and then the green wire to see if it responded?? Just kinda curious before I go make a booboo or something.
