well my friend is installing a air/fuel ratio guage by autometer.. but now hes wondering what wire should he tap the air/fuel ratio wire? thanks! let me know asap!

 

you're better off not bothering.
1. its a light show and nothing more
2. The current drag on the sensor tends to kill the sensor.
In any event, its the black wire.

 

which black.. theres two?

 

when looking at the connector, theres the bracket, then the white wire, then the black one "above" the white one, opposite the bracket.

 

the only point of having that gauge is if you are running nitrous or boost

Actually there's really no point in having a narrow band a/f gauge.

 

Well I didn't know that he is refering to a narrow band. I for one used a wide band when I ran nitrous so I could tell if I ever was close to running lean or not.
