When your looking on the gauge you got 3 wires.
Power
Ground
Dimmer/Bright wire.


What's the problem?

Autometers only have two, power (white) and ground (black). Hook up the power to the dimmer switch.

O ok.
Wasn't sure on which ones came with an active dimmer.
Honestly I think my gauge came with 3 wires...

I may have to go home and check.

Get a pack of those vampire taps. Hook the power wire up to the illumination wire on your radio harness (the green wire on the harness I think, don't quote me on it) and screw the ground wire somewhere down on the radio chasis. That way, you can have the gauge light up the same time your dash lights turn on.

Vfaq should have a wiring diagram for the 1G radio

No need to run the wire all the way to the radio. Just go to the dimmer switch on the left side of the dash.

Which wire on the dimmer switch plug is the dimmer wire? There is a green white stripe, a black and a black with yellow stripe?

The black wire will work fine for the ground.
