I was wondering if anyone has put one in their car and could give me some pointers or tips. My gauge is the one that is going to sit inside my vent next to the drivers window. Some questions I have is what did you use for the ground for the lighting and is it nessecary to sauder (Sp?) the wires into the dimmer switch? Thanks guys, just can't wait to see that boost gauge in action.
