The Roadmaster Smart Diode Wiring Kit (Part # RM63MR) is a complete dinghy/flat-towing electrical system designed specifically for towed vehicles with variable voltage (multiplex) wiring and factory LED tail lights.

Unlike standard diodes, Smart Diodes automatically modulate motorhome 12V signals into proper voltage to prevent electrical feedback, false brake light activation, and battery discharge while flat towing.

Kit Includes:

  • 2 Roadmaster Heavy-Duty Smart Diodes
  • 7-Way to 6-Way Coiled Power Cord (Flexo-Coil)
  • 6-Way Round Vehicle-Side Socket & Mounting Bracket
  • 27-Foot 4-Wire Flat Harness
  • Ground wire, split wire loom, terminal connectors, and mounting hardware
