1997 model

Ecu Power= What color code and is it on the top or bottom bundle connected to the ecu

O2 sensor= same question

The ground is the easy one. I had these somewhere, but do not have access to these where I am at.

I ran my power wire to a fuse inside the car. the O2 is the white wire with black stripe at the ECU. and i grounded it at the factory ECY ground.

I believe the o2 signal is pin 30 or 31 on the ecu. I think its grey with a white stripe on it. **I THINK. Check the wire with a pin tap and a fluke meter first. The voltage should be between 0 and .1 vdc, and it will be going up and down at idle. I powered mine from the cruse control pannel on the left of the steering wheel. Its also where your elec mirror adjustments are. Take a screw driver and pop it out. You will see a socket with 3 wires. You need the green wire and the black with yellow stripe. Im not sure which is + but again, break out the fluke meter and test it. Both your pos and neg will be in there. Hooking it up this way will make it only come on when your turn on your lights. This is good because o2 readings are virtually useless. Get an egt gauge. :thumbsup

Thanks guys, finally got back from the shop where I posted the question. We found the exact three wires in the upper harness bundle at the bottom. Ecu ground, Ecu power and O2 sensor all together.

Thank god for the chiltons manual......it had the schematic I needed. My buddy gave me shit about posting the question when we were scrambling for the info that I forgot to look up earlier.
