Updated 11/06/2023 | Published 11/03/2023
Question:
Hooking my dump trailer up to my tractor with a 7 way plug… assuming I need a diode to prevent the trailer power from back flowing to the tractor. Do I need one for each wire, just the hot, or hot and ground?

Helpful Expert Reply:
To install the Roadmaster Single Park Light Diode # RM-690 you are just going to need to find and cut the wire going to the parking light bulb, and install the diode in-line with the wiring. The "IN" side will be the part of the wire that leads to the front of the vehicle, and the "OUT" side goes to the bulb.
