There is, Raymond To hook up the Tekonsha Prodigy P3 # 90195 to your vehicle, you're going to need to test each of the wire for their functions, and attach them to the hardwire harness that comes with the controller. The black wire on the controller is for power, the white wire is ground, the red wire is for the stop light circuit, and the blue wire is for brake output.
