I found it by testing it. there are 4 wires on the O2 sensor, 2 of them are black. 1 of the black ones is the one you want. try each one, it wont harm your car, the guage just wont work. thats what i did, unfortunaltely on the second try, but electrical tape work real well on the first

What brand of O2 sensor do you have? I have a Glow Shift brand and it doesn't seem to be working. I tried it on all the wires and only got one wire to actually read something, but it definetly wasn't what I was looking for.

You may need to get an actual o2 sending unit for your A/F guage, thats what i had to do. But you will have to get somone to weld a bung on for the extra o2.

Yeah im afraid that since it wouldn't hookup to the factory o2, your gonna have to go with the sending unit. But i know nothing about TC's may want to check with some other people that have TC's and have hooked A/F guages up. Sorry to have to tell you that, but maybe they will have a better less expensive fix for you. Good luck with it.
