I have a 2005 mercury montego premiere and just installed a new head unit. Everything worked fine. I have a pioneer head unit that plays DVDs but I didn't wire it to my parking brake when I first put it in. Today I decided to do so got it all out, then had an urgent call and couldn't connect it. As I was putting the radio back in, something sparked and started to smoke, (yellow cords where showing a little bit, might have touched metal) I took it to a car audio shop and tested the head unit, and it worked just fine. Could I have broke(shoted) the harness that connects the colored wires together and the other side connects to my car wiring(they plug in) OR could I have broke something with my car wiring. I checked audio fuses, they are fine. PLEASE HELP I BEG
The Yellow wire, is the Constant +12V. So, it is possible that you burned up part of the harness or factory amplifier if it grounded. Double check the fuse box under the hood, if you don't have power there. If it doesn't work, try the factory radio, if it works, the amp( if it has one) would be ok, and maybe you might just need a new harness. Double check all of your connections, and make sure they are secure, and completely covered. Good Luck!
