Just need a little help id-ing some wires.
The connector for the o2 sensor broke in my hands and now i need to know which wire (harness side) connects to which wire (sensor side), so if anyone could just pull theirs and let me know, that would be awesome. Harness Side: 1. White 2. Black and Yellow 3. Blue and White 4. Brown Sensor Side 1. White 2. Blue 3. Black 4. Black I have tried a few combinations however am tired of blowing my efi (15A) fuse...

the 2 black wires are the heater circuit. they should be pins 1 and 2. the others are the OX signal and ground.
on on the sensor plug, pin 1 is the heater signal back to the ECU. pin 2 is the +B 12V when you turn on the key. so isolate all the wires, turn the key on and find the wire that is giving you 12V pin 3 is the signal wire to the ECU, im not sure if it mates up with the white or blue wire on the sensor plug. Pin 4 is the brown wire, its the ground. -------------------- 2001 Celica GT-S Turbo
