okay. where to start.... I had baught the car used. there was already an aftermarket headunit in it. using the same harness kit. I upgraded to a dual unit. worked great. then I wanted mp3. so I bought a pioneer. then I bought a sub. the pioneer didn't have a high pass and low pass filter. so I just recently got a new unit.

here is where the trouble begins. I was expexting tojust plug n go. but nope. unit wouldn't turn on. so I hook the unit up to my amps pos and neg connectors. it turned on and worked fine. then I cut the harness. still won't turn on. then I noticed. that someone added an extra harness bit. it goes from the original harness. to the harness I cut. to the headunit. there was also a wire leading left through my dash leading up to my internal fuse box on the 12 volt rail with a 10amp fuse. I need to fix this shotty workmenship.

I need a diagram of the harness. when I stealth install my new alarm I will probably fix the harness problems at the same time....

sorry for misspellings. this was typed on my smartphone..
