Do they make wire harness for a 2005 F150 yet?
i have been installing for about six years now and i have never had a problem putting a radio in a 2005 f-150 you can get the harness at any best buy or car audio palce that installs radios. i have done a couple hundred of these trucks for radios and never seen a problem.
to replace the factory radio with an aftermarket one, go to circuit city. to replace the factory harness itself i would suggest going to your local ford dealership
You are going to need a multimeter Set it to 12 volts dc ( probably will be 20V, which works for this.) Ground the negative cable on the meter, to a secure ground. I like to stick it in the ignition, myself. DO NOT strip any wires at all, you can stick the point of the meter in just to make contact and get a reading without exposing any Hot wires. Slowly check each wire for 12 volts. ( if none read that, check your fuse box) that will be your constant 12v, or yellow. Then reground the meter, insert ket, turn to acc, then re meter all of the lines, looking for 12v again ( for red/switched +12v on the harness.) After finding that, switch it to Ohms, or the horseshoe looking one. Pick a wire as a starting point, and stick the other end of the meter in until it either reads a number, possible 2 - 8, and that's a speaker ( I would also write all of the colors down for this) And keep repeating until you fine all 2 to 4 plus speakers. Having cut the plug can also have done excessive damage, like to Onstar, if installed, or any security system also. using metal cutters, cutting through power/ground/speaker/ and other wires all at once, and sometimes be catastrophic to vehicles, seeing how much technology is in them. I hope the best for you, and next time, pony up for ther harness ;) Good Luck! P.S. if that seems too much to do, a hardwire goes for a couple hundred from a shop, as pure labor. just as a heads up.
