hey mike, in order to run the wires from the engine to the trunk you're going to have to go through a hole in the firewall. i didn't have much of a problem working it around the rest of the wiring... just be patient. the best way to get through the cabin is by taking out both the front and rear seats. yeah, it sucks, but i ran my wires under the door trim/kickplate? on the right side and eventually they starting squeaking since they didn't fit right. once the seats are out, pull up the carpet and the wires down the right side of the cabin and through a gap in the metal plate that separates the trunk from the cabin.
