Not really sure if this fits under sound or electical, but this seems like a better place for it. The other day, I changed out my deck for a better one. I've hooked up many decks with no problem. This time, both harnesses had "positive dimmer" wire, so I decided to connect the two so that My deck would dim with the dash lights. So after installing, I put the dash back on and connected the headlight and dimmer switch back up. The door chime didn't come on like it usually does when its open, and when i'd dim the switch, the dash would dim, and the deck would get brighter. Figured something was wrong so i just disconnected them. Since the door chime didnt work, I checked the fuse and sure enough it was blown. When I put it back in, and hit the cation switch above the column, it blew the fuse. Now every time i put a fuse in, it blows it. Now I dont have any brake lights since the fuse keeps blowing. Any one know whats wrong or how I can fix it? Could it possibly be something like a bad caution switch or something?
