Review on Enhance Your Car's Control: MicroBypass Parking Brake Override Bypass for Clarion by Brian Barnes

Definitely use it even if you're so anal you think you should connect it to the brake as advertised. Instead of running 8 feet of wire behind the dash to the brake wiring and trying to find the right wires that are tightly mounted and hooking them up while lying on your back with a flashlight in your mouth. Just pop this in the upright position in about 2 minutes and you're on your way.
