Boost gauge lighting

[b00zt3d spyd3r]

so since I've had the car I couldn't see my boost gauge at night(doesn't light up) but the other day I pulled it out and realized it has the wires for the light. What should I hook up to so it turns on/off when headlights are turned on/off?

you could run a relay and power the relay from the light switch or the power pin from the headlamp itself ...... I personally run al my gauge lights from the ignition switch w/ relays and fuses so they turn on once I hit the ignition.

But I only want them on at night when the headlights are on

Tie them in with your dash lights, you will need to test wires with a test light to find the wire you need. I tied mine into one of the wires back behind the radio harness that is powered when the gauge cluster is illuminated.

pull off the column cover, find the 10 pin plug on the back of the head light switch, (connector B on diagram). Pin 7 should be a black wire. cut it a few inches from the plug. the end of the cut wire that is still connected to the plug need to be connected to the (+) for your gauge light. connect the (-) on the gauge light to the other end of the cut wire.
now the gauge light will come on when you turn on your headlights.

Try your cruise controle wire its a green wire so when u turn on your lights the guage turns on also

Thanks guys! Anybody know what the correct belt for power steering?

Hook the power wire of the bulb to the illumination wire of the fog light switch. Ground the other wire either to the fog light switch ground or to the chassis itself.

As for the power steering belt, it's the smallest of the 3 belts and is the highest. You will have to remove the alternator belt to change it aswell.

This is how I wired my mechanical gauges to dim with the interior lights:

The pics do not work, but should be easy enough to follow. I don't personally prefer bright gauge clusters at night.
