what he said...
Just so you know you have to keep the total length at 5 feet or so. I read that in a forum (I believe Cause For Alarm). If you want to extend the wires past 5 feet for switch, you must use a relay as the resistance will be too great. There are alot of good ideas; the best are "Ghost Switches". I saw someone make an 1/8 Stereo jack on one of there empty panels by the emergency brake. At first glance, it looks like an Ipod jack or something like that, but he actually had a 1/8 loop adapter he plugged in there (completing the circuit) everytime he started the car. Get creative, the harder the better.
