I baught a Air/Fuel gauge from Autometer and I'm wondering where to run the second wire that gives the reading [it's purple i think] and where to splice it into..also where is the wire located?
You need to go behind the passenger kick panel where the computer is. You'll have a big wiring harness there attached to your computer. If you know your pinout (might even be written on the harness..), you can splice it on either pin#43 (left o2 sensor) or pin#44 (right o2 sensor). The #43 wire is red/black and the #44 wire is grey/light blue. Just splice it in one of them. There's also a way to use a toggle switch and switch between the left/right whenever you feel like it. I have the 94-95 pinout here on my computer if you want to understand better. If you want me to send you the file, give me your email adress.
