Pro tipWiring and battery tips

  • Protect the car’s wiring. Diodes or a separate bulb kit keep the motorhome’s lighting signal from feeding back into the towed vehicle’s electrical system.
  • Watch the battery. Some vehicles drain their battery when flat towed; the owner’s manual will say whether you need a charge line or battery disconnect.

Product Description

Get your towed vehicle's lights working right, every time. Roadmaster wiring components make a clean, reliable connection between your motorhome and your toad.

Diodes are frequently used in wiring kits to prevent the backflow of current to the electrical system of the towed vehicle or motorhome; however, many newer vehicles now use a multiplex wiring system, whereby multiple electrical signals may be sent down a single wire. If an ordinary diode is used in these applications, then the bulb will illuminate as though the vehicle is braking whenever the taillights are on. That is, you can't tell the difference between the brake lights and running lights. Smart Diodes correctly modulate the voltage to activate only the intended circuit. The result is vehicle lighting that looks and functions as intended. Each vehicle requires two Smart Diodes. Vehicles with LED lights require a different kit than those with incandescent bulbs. Installers can choose a
