What is the easiest way to hook-up an air/fuel ratio guage in a 97 Avenger
 

What is the easiest way to hook up an air\fuel ratio guage into a 97 avenger with a 420a, I know where I want to mount it but don't know what wire to tap into or where to tap into it?? Any feedback would be greatly appreciated...

You need to find a wire diagram for the Emission system and tap in to the pre cat 02 sensor. Im not sure what color wire it is however it gonna be thewire that sends signal to the pcm. Hope this helps

why do you need this? is it just for looks? if so it dosnt matter... but if you want to get actual resulst you need to get a wideband kit and drill into your exhaust. that way you can have an eaiser time tuning your car
