alright as u all know the air fuel is digital. i wired up my other guages to the dimmer but im not sure how you work this haha. since there is no light cable on the air fuel should i just wire the 12 volt to it? i kno the gauge would only work when i have my lights on but i could always just use the first setting on the lights switch. has anyone done this or did u just say screw it and not worry about the dimmer?

On most gauges there are 2 different wires used for power and lights. Dont put them together unless you want them both on at the same time. I would never use the dimmer switch for anything.

why dont u you use the dimmer switch...in my old stang i had pillar gauges and WOW the glare was horrible at night...and the air fuel is digital so it gets its light from the 12 volt wire

Not all gauges can handle variable volts to the light source. Seeing that Autometers only use a bulp sepperately wired, it will prolly' work fine. If you dont have a white wire on the air/fuel gauge. It doesnt have a back light. Only the LEDs light up. And it must use a 12v power source.
