Not that I know of. Find the two wires that run to the reverse bulb. Remove the loom over wire. on my silvy tail harness it was a green wire and black wire. 90% of the time the black wire is the ground, so I spliced into the green wire. I only spliced the wire on the driver side reverse light. To hook up both cubes I ran the power wire from one cube to another than spliced that to the green. Then u just ground both cubes to the frame or under the bed somewhere. so the cubes work when my truck is in reverse. I thought about putting them on a switch. I still may do that, but for now I like this.
