My 2005 Mustang
aftermarket stereo stopped working. I pulled it to do some checking & found that the constant power wire coming from the factory stereo harness has no power to it anymore,no idea why. I wired the constant power from the deck to another source, works fine now. Fuses are all fine, everything else seems to be working. Find it strange that the wire lost power. I have no idea where it goes or what it's tied into. Any ideas why it would lose power? I'm stumped.
