I need to know from the experts..or those who claim to be...I am hooking up a Air/Fuel Gauge and need to know which wire goes to the O2 Sensor from the ECU. Fatdaddy66 gave me some great info but i cant seem to find the correct wire..I have the Power and the Neg hooked up so it lights up all nice and pretty but doesnt do much..I really dont want to run a wire out of the cabin all the way to the sensor, so any help is greatly appreciated..

Thanks

Shadow
BTW.. 99 Altima GXE 5speed

You will see a white wire w/ a red stripe in the upper right hand corner of the ECU harness. Count four wires to the left of that. It should be a black wire w/ a white stripe (Camshaft Position Sensor Wire) The white wire below that is the oxygen sensor wire. Don't run a wire directly to the oxygen sensor for two reasons. 1) It is my understanding that you'll obtain a better reading from the ECU harness wire anyway. 2) The oxygen sensor uses shielded wiring.

1fastaltima,

It was fairly easy once i found the wires...go to discount auto and get the wire taps that have the slide in connectors...makes life so much easier. I think they ran about $2 or so. Just have patience and take your time...the wires are tightly bound in there... Good Luck..post pics when you done..

Fatdaddy66,

Thanks..I'll look that up...
