I have an Air/Fuel ratio gauge and I need to know the best way to mount it. I have a 92 Camaro and I cant find a good place to go through the firewall. The instructions say...
Red wire: Connect to a fused and switched 12v positive source that is turned on and off with the ignition switch.

Black wire: Connect to good engine ground

Violet wire: Connect to oxygen sensor signal wire. Connect to vehicle wiring harness, not oxygen sensor since some oxygen sensors use shielded wire.

My main question is where could I bring the wires through the fire wall? And What wires in my car should I splise into? I need any help I can get guys!!!! I need to have this done by tomorrow night!

 

Ok I will tell you how I wired up mine, I got my hot wire, from underneath the dash right below the stearing wheel theres alot of good accesory wires in there, I believe mine is pink.

Ground is easy, just use an eye ring or theres a couple of stock ground rings.

I wired my purple to the o2 sense with a t tap my friend did it to the computer like your supose to on some cars, on the camaros it didnt make a difference.

As for where to run the wires the only wire you have to run through the firewall is the purple one, what I did is pull the down the carpet a couple inches if that and you ll find tons of spots there usualy indented like a good one is where the clutch pedal would be if your car was stick, (if you have an automatic) if you have any problems just tell me I'll help you out more and go look at my car and give you exact directions

1991 teal camaro RS rebuilt 96 350 marine motor, comp cam, accel ignition,8mm accel plugs and wires, hedman headers and y-pipe, and rear end with 4.10 gears. Stock 700r4, best 1/4 time 14.6

 

On mine I ran the red wire to one of the blank acc spots in the fuse block. The ground I used an eyelet on the wire and put the wire on one of the dash board to firewall bolts. The purple was wired into the O2 sensor just aft of the conector. On third gens the O2 sensor wire is not sheilded. I ran the wire through the fire wall by using an exsisting hole that is below the brake pedel mount. As far as mounting I just used the autometer dual gauge pod (see pic). Warning though if you use it you will have to cut the a piller cover. If you have any other questions just let me know and I will try to answer them the best I can.
