I am installing an air/fuel gauge tomorrow. I remember seeing a post on the install. Does anyone out there have info or a link possibly?

Thanks!

I believe you tap into the BLACK wire on the drivers side oxygen sensor for your signal wire to the A/F gauge the other wires are for your power supply that is your own choice how you want the back light to work

I think its the red wire with a black strip on drivers 02. You can also tap into wire on computer harness, I believe its port # 87...Hope this helps!!-Neil

 

I think that you can tap #87 on the harness. Just to make sure, I can find that harness on the pass side of the engine bay(where it goes into the cab) kinda behind the battery. Is that the easiest place to tap the wire?

THANK YOU!
