Do I have my boost gauge installed, I already have the air line hooked up I just ned to get the power and ground hooked up. I want it to only light up when my dash comes on and I want to be able to use my dimmer. There are four wires that go to the dimmer and I have been messing with it for a while now and I can't get my gauge to work for me... It either doesn't light up or it had power all the time even when the vehicle is turned off and locked up. The dimmer works on it but out doesn't turn of with the dash... Please help..
