  • 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.

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.

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.

  • Will The Roadmaster Smart Diode 7-Wire to 6-Wire Wiring Kit Fit the 2022 Jeep Grand Cherokee WK & JL
    I can completely understand the confusion, but to make it easy, if you have the new body Jeep Grand Cherokee, then you have what is known as the Jeep WK and if you have the new body style it is known as the JL. I'm not entirely sure why Jeep does this, however the good news is the Roadmaster Smart Diode 7-Wire to 6-Wire Wiring Kit for Variable Voltage LED Tail Lights # RM63MR will work with both the old (WK) and new body (JL) style. If you interested in a complete set-up, let me know...

  • Comparing Smart Diode Wiring Kits RM47ZR And RM63MR
    The Roadmaster Smart Diode Kits # RM47ZR and # RM63MR are quite similar in that they both contain the same smart diodes, and wiring components. The difference is that the # RM63MR also comes with a 6-pin round plug for the front of the vehicle, as well as a coiled cable to connect the towed vehicle to the Rv 7-way plug. So unless you already have a 7 to 6 coiled cable and a 6-pin socket laying around, we recommend getting the # RM63MR, as it will come with everything you will need to wire...

  • Correct Tow Bar Wiring For 2022 Jeep Gladiator With LED Lights & ParkSense
    So a couple things here, as by blind spot indicators I believe you are referring to the ParkSense feature on your 2022 Jeep Gladiator. If so, you would not be able to use the Demco # DM9523010-54. The issue is that the brake and running lights will all be the same brightness with standard diodes. To avoid this, you'll need a Smart Diode kit from Roadmaster: - Roadmaster Smart Diode 7-Wire to 6-Wire Wiring Kit for Variable Voltage LED Tail Lights # RM63MR The diodes in this kit convert...

  • Best Flat Tow Wiring Kit for a 2023 Jeep Gladiator
    The Tekonsha Tail Light Isolating Diode System # TR118821 is a reliable kit but it isn't what I would recommend for your 2023 Jeep Gladiator because there are similar kits that are easy to install or are built much better than this one. For something that's easier to install we have the Curt Custom Tail Light Wiring Kit # C96JR which tees in behind the tai lights, but if you wanted something you splice in then I recommend one of the following from Roadmaster, depending on if you have the...
