I got a wiring harness from Crutchfield but the factory wires did not match up with what the harness needed. To get the deck working you just need a ground, positive, and an ignition wire. Just groung to a screw or fing a ground in a factory harness. For positive I ran a wire with a fuse straight to the battery just for peice of mind. I think I disconnected the lighter and used its positive to send power to the stereos ignition wire, just be sure that yours works off of the ignition. Then you just hook up the antenna (should just plug in) and run speaker wire to all the speakers. I wouldn't even bother trying to use the factory speaker wires. So you only really have to worry about the ground, positive, and ignition wires and then it gets easy from there. Good luck!
