Alright well here is my problem, i baught the aftermarket harness. Hooked up everything. Everything works except one thing. When i turn off my car the unit doesnt go off. Iv tried changing the yellow and red wires but nothing. I called a local audio shop and they were saying you had to run a wire from the deck to the fuse box. not sure whats going on. But its annoying when you have to start it up yourself everytime. Anyone know whats going on?
