alright well im hoping someone knows in here, but I installed reverse indiglo gauges on my car and when I ran the power from the dimmer it isnt working at all, I checked the ground still nothing. I also set it back to its original state to see if it would go on but nothing either. anyone any ideas?

 

my first gues is one of the wires you unplugged isnt plugged back n mostlikely the harness that goes to hazard lights. stil if no mpower check with voltimeter you might have shorted something and check the new grounds as well.

 

What gen car do you have? The same problem happened to me on my 3rd gen when I installed my HU. It turned out to be the Timing Control Unit (TCU). Replaced the TCU and has been working like a champ.
