Did you buy the wiring adapter/harness to fit the OEM stereo wiring? I'm posting the following since I don't know what you have actually done.


Splice and Attach theHarness:

1. When splicing the Scosche harness to the aftermarket harness that comes with your new headunit remember that you can do this inside.
2. Match the colors of each wire and crimp them together with the crimp caps. Do this for all the wires EXCEPT the Red, Yellow, and Blue wires. The constant and switched power wires are flipped, so you will need to connect the Red wire of the Scosche harness to the Yellow wire of the aftermarket one and the Yellow wire of the Scosche harness to the Red wire of the aftermarket harness. The Blue antenna wire on the Scosche unit is actually the remote wire. Attach the Blue-White wire from the aftermarket harness to the Blue wire on the Scosche harness. (See Picture) It is usually recommended that you use the RCA Pre-Outs in the back of your aftermarket unit so that you do not blow out your speakers. However, I have yet to have any problems. I haven't seen any posts with problems from this either.
3. Now is a good time to run the wires for a Line-In connection to an iPod or any other device (See below)
