Need some help wiring Narrowband. I have the following wires to hook up:
Red- V+12V
Black-Ground
Yellow- Battery +
Pink- Sensor +
Blue- Sensor-
Please tell me which whire to hook these up to and if i should disregard any wires. This is a glowshift Air Fuel Ratio Gauge.
Thanks!

Ah. This is what you are wiring up.
You need to wire the Yellow to a constant source for power. IE like tied directly to the battery. Red is a Switched power source. Black is ground.
I'm trying to remember which wire to use for the sensor. I believe it's the pink wire since our O2's are positive signal based. I just can't remember which wire it was on the car.
BTW. I'm in DFW and don't have any books with me. I'll try to find out which PCM wire it is to tap into. Also watch out for the pitfall I ran into where my A/F gauge went out on me and caused all kinds of issues. I didn't find it until I noticed my O2 output on 1 side was in the 10-30mV amount. Normal is 800-1100 mV IIRC.
