If the gray wire does'nt work for you. Turn the parking lights on and find it at the fuse block using a test light or the wires with it and hook into it so when you turn you lights on it will light up. I have plugged into the fuse block before just find the one that works when the lights are turned on and goes off when turned off. JMO. Cole
