signal wire for A/F guage?

[gsr24]

which wire on my ECU harness is the one that needs to be hooked up as the signal wire for my A/F guage?

Look in your repair manual. It will have a diagram of the wiring harness attached to your ECU and that will show you what wire is from the O2 sensor. I can't remember what (Letter-Number) it was for my 91 teg, but it was white with a black stripe if I remember correctly. Someone please correct me if I'm wrong.

There are a couple white wires with black stripes, so make sure it's the right one. It should have a voltage reading between 0.5 and 1.0V. Again, someone correct me if I'm wrong. It's been a while since I installed mine and I'm going off of pure memory here.

It isn't the same color wire when it goes into the wiring harness though. If you want, you can take the signal right there, but there's a chance it can corrode from being exposed to the elements. It's better if you take the signal from right before the ECU. It is definitely not solid white on the harness.
