Well how to install it sure would depend on what brand gauge it is. Could you give us some more information on what you have? Maybe even some pictures of what you have.

If it's a standard autometer (or similar) guage that works off the stock o2 sensor, let me be the first to warn you. It is nothing more than a flashy, blinky light. DO NOT trust it for tuning, it's only good use is to see that your car is cycling in "closed loop" or to warn you if things go WAY lean. Other than that, it can be reading in "the green" and your car could still be dangerously lean under boost.

THey may be more usable on an N/A car, but like i said, DON'T Trust it for tuning a turbo car. There's a reason it was probably given to you, as i gave mine away and it was given to me. Other than being a cool light, they are pretty useless. But hey, if you've got a spare hole in the A-pillar to fill it does look pretty neat!

as for wiring it.

Red goes to an ACC (switchable with the ignition) power source

Black (or sometimes green) goes to ground

And the left over one goes to the O2 sensor signal wire. ( which can be found in that first link turbosax posted)

On my 91 gsx i couldn't find the female spade connector while trying to install my A/F gauge.

On my 91 gsx i couldn't find the female spade connector while trying to install my A/F gauge.

It is there wrapped in tape in whe wireing harness. I found it on both my 90 & 91. Keep digging

I didnt use the female connector when I connected mine...I went straight to the ecu, and on vfaq the o2 sensor is pin 4.big_d

 

[matt98eclipse]

Big d: Would that apply to my car as well? pin 4

 

[big_d]

Hells Yeah

A photocopy of a fuel temperature gauge is more useful than an A/F gauge without a broadband O2 sensor.

Don't bother.

I paid $12 for my autometer one, and I needed to fill a hole big_d

A piece of paper and some tape would work better for hole-filling. Narrowband 'A/F Ratio' gauges are almost completely pointless, and distract the driver with a ricer disco-ball effect to boot.
