After installing a new mp3 head unit, I noticed that all my internal lighting (ash tray, cigarette lighter, heating controls, hazard light, headlight dimmer and fog lights (are they lit??)) don't work. I thought maybe when I connected the dimmer/illumination wires, I blew a fuse?? It's kind of bothering me. Any thoughts would be appreciated.

 

Looks like you shorted something out. Check the fuses.

Fuses look intact, at least the ones I looked at. Anything else?

 

check to make sure it is properly grounded, and that all the fuses are good (sorry, I don't remember what fuse it is that you need to check)
