I wanna know if anyone knows how to hook up the boost guage to the dim switch on your dash. I would like it to like up when the headlights are one and be able to be dimmed when i want. Anyone know what wire it might be?

 

Not quite sure, it is easier if it is just lit up all the time. Boost gauges are quite an easy install

 

Run the light wires to the switch,

 

I would think you would ground it to what controls your lights, but I don't like playing with stuff I don't have any idea on, and electronics and grounding it to something wrong = $$$

 

I just piggy backed off the little cubby light.

 

i figured it out. Ripped out the dash and used a test light to see what one was the positive for the dimmer..A little more work than needed but im happy with it

 

behind the little panel by your knee, there is a wire harness sitting in there that is pretty short and not hooked to anything. I used a voltmeter and found there are two wires related to the lights.

I hooked one gauge up so that when I turn the running lights on it lights up and when I turn on the headlights the other gauge lights up.
