where would you hook up an air/fuel gauge????
thanks

to the o2 sensor?

where specifically ???

you would tap into the wires that run from your rear o2 sensor to the ecu. i dont know if you got a wideband o2 sensor/gauge or just a regular one theyre not really 100% accurate they just are more for looks.

Instructions should come with your wideband A/F ratio guage kit. If you are trying to install a narrowband A/F guage, you are wasting your time.

there not usless. id rather have a narrowband than almots any other sensor
it saved me from blowing u pa cylinder when i had a leaky in jector. i saw it was pegged at lean and stopped driving

for $40 you cant go wrong

in extreme conditions yes they can be useful i suppose. however to accurately measure the cars normal running condition, a regular a/f gauges does nothing more than look pretty
