ok trying to install an air fuel gauge in my 1989 mustang. Does anyone know what wire its that im supposted to hook it up to on the computer harness. also what color it should be thanks guys. by the way its an autometer.
it came with instructions to consult with someone on what wire it is it doesnt give specifics so if anyone has installed one just wondering how they hooked it up to the computer harness thats all thanks
Dark green/purple wire going to the 02 sensor.
I tapped into mine right where the harness goes by the passenger side caster camber plate.
(this is for my 89)
I found it by looking at my Chiltons book.
There should be a dark green/purple and a black going down to the 02 sensor.
