its only a ground ^_^ just hook it up to the body... or trace your door switch and connect the ground to it so when you close your door it will trip the ground ^_^v

btw who installed it??? if its someone else you have to remove the panels and trace the ground wire from the back and tape it to the car frame and test it... usually there are two ground one is a trip ground which is your ebrake ground and one is connected to the car frame or battery ground...
