Installation Instructions:
Open the driver rear door. Remove the running board. The wires are in the harness under the running board.
Additional Information:
Do not T-tap onto the thinnest white/black for the ground—that is the incorrect wire. Also, the module will work when the vehicle is off but will not pulse when the truck is running.
