If you are installing an aftermarket amp you need to get the "remote" wire from the fuse box.

If you did not cut the plug off of the factory harness, plug the factory radio back in and see if there is a wire that has 12 volts on it any time a CD or the radio is playing. If you find such a wire, that would be the one you need.
