  • Diode Kit
  • Splices into Vehicle Wiring
  • Universal
  • Roadmaster

This complete kit includes everything you need to connect your RV's tail, brake, and turn signal lights to your vehicle with variable voltage lights while flat towing. 7-Wire to 6-wire cord and 6-way car-side socket included for easy hookup.

  • Complete wiring kit lets you connect your RV's tail, brake, and turn signal lights to your towed car's lighting system

This complete smart diode wiring kit lets you connect your RV's tail, brake, and turn signal lights to your towed car's lighting system so that you'll have the signal lights necessary for flat towing your vehicle.


Because your vehicle has variable voltage tail lights, you cannot use a standard diode wiring kit to get these signal lights. If regular diodes are used on a vehicle that has variable voltage tail lights, the bulbs will light up as though the towed car is braking whenever the tail lights are on. In other words, there will be no difference between your vehicle's brake lights and running lights. This is because variable voltage tail lights use the same wire to power both the brake lights and tail lights. They do this by using a 12-volt signal for brake lights and a 9-volt signal for tail lights.


Smart diodes correctly modulate the 12-volt signal coming from your RV to activate only the intended circuit. The result is that your vehicle's tail lights will look and function as intended.


This wiring kit includes everything you need to hook up your motorhome's electrical to your towed car. It is designed to work with LED lights only. If your vehicle has incandescent lights, you'll need to use the smart diode kit designed for incandescent tail lights (RO94FR - sold separately) instead.


If your RV has separate tail light wiring, wherein the brake and turn signals run on separate wires, you'll need a wiring converter (RM-732 - sold separately) to complete this installation.

This product was exactly as described, and worked well to hook up the taillights in our towed vehicle. Thanks



by:

Product works but is a bit flimsy. Also, the connectors are an unusual size, 3/8 vs 1/4 inch, making it harder to purchase replacements if needed.

4 conductor wire was to short. I did not waste any wire and it was 6’ to short.

It is unusual that the wiring would come up short. Would you be able to send a picture? How long was the wiring that you received?



by:

Customer Service was excellent - 5 STARS. The smart diodes are another matter. They are very poorly made. Connections had to be taped together in for them to stay together. They are inferior, cheaply made and will not crimp. Your instructional video was very good.

Great company with excellent service.

  • Parts Needed To Flat Tow A 2022 Jeep Cherokee Trailhawk
    The Falcon All-Terrain Tow Bar # RM-522 that we offer doesn't come with safety cables included so I don't know the exact length that you have, but we tend you usually need to add on quick links, like part # 37201345, whenever a high/low adapter is used. These quick links are approximately 4" in length to help bridge the gap left by the # RM-070. Without having the baseplate installed and the motorhome nearby to measure the hitch height it can be a total guess whether or not an adapter...
