Roadmaster Flat Tow Wiring Harness - RO54FR

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

Smart diodes allow a motorhome that is towing a car to use that car's rear lights if the car has variable voltage LED lights. Unlike regular wiring diodes, smart diodes activate only the intended circuit - brake lights or tail lights.


Features:

  • Smart diodes allow a motorhome to power a towed car's lights
  • Works with variable voltage LED tail lights
  • Requires wiring and wiring supplies (sold separately)
  • Quantity: 2 diodes
  • Made in the USA
  • Limited lifetime warranty


Smart diodes allow a motorhome that is towing a car to use the vehicle's rear lights, provided it uses variable voltage tail lights. Variable voltage tail lights use the same wire to power the brake lights and tail lights. They do this by using a 12-volt signal for brakes and a 9-volt signal for tail lights.


If a regular wiring diode is used with variable voltage tail lights, then the bulb will light up as though the vehicle is braking whenever the tail lights 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.

Unfortunately replacing the stereo did not fix my left tail light issue. I fear it's a possible wiring issue and unfortunately I live in Arizona and there is no e-trailer down here for me to take it to for repair. I would imagine the new diodes are perfectly fine



by:

work great and easy to install.



by:

I had to develop a method to make them work for my 2015 Ford Edge SEL.



by:

The diodes have functioned without fail.



by:

Great service and great job keeping us updated with the transit. We will definitely shop here again! Thank you.



by:

Worked as advertised.



by:

Easy company to do business with.



by:

There needs to be more clarity on which ones are needled to work with vehicles. I ordered the kit that has more diodes. After opening the kit and called the help line and was told it will work. So I even emailed asking to order the smart diodes if they could discount them because I already opened the package on fist order and I could still use the rest of wiring. No response so I just ordered the right ones. There is no room for more than one diode.



by:

They work great and are a nice compact size. However, the instructions on the packaging is different than what is shown on the actual device leading to confusion.



by:

The dealer installed the wrong diodes for our tow set-up and our lights never worked properly. Looked on etrailer and found a how-to video that explained the problem, ordered this product (the correct diodes), and now everything works just as it should.



by:

installed fairly easy ,once i got wiring diagram for 2020 jeep gladiator/with LED lights LED tail lights need smart diodes ,not 4 reg diodes



by:

Great service, when I called they were very helpful



by:

Thank you!



by:

Works like a charm!

This product works very well but the wire diagram was not correct.

  • Recommended Parts To Flat Tow a 2021 Ford F-150 Hybrid
    I recommend using the Roadmaster Base Plate # RM38VR on your 2021 Ford F-150 hybrid. You will need to connect this with the Roadmaster Nighthawk All-Terrain Tow Bar # RM-676 to your motorhome. You may need the Adapter # BLU28XR to keep the tow bars within 3" of level from your motorhome to the front of your F-150 depending on the height difference. The Accessory Kit # RM-9284-2 will provide you with covers, locks, lube and wiring. You will also need a Charge Line Kit # RM-156-25 and to...

  • Parts Needed To Flat Tow a 2024 Jeep Wrangler Unlimited Behind a Freightliner Chassis Motorhome
    First I recommend using the Roadmaster Direct-Connect Base Plate # RM-521453-5 on your 2024 Jeep Wrangler Unlimited. This will pair with their Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar # RM-676. You will need to measure the height of the receiver on your 2024 Newmar Kountry Strar 3709 to determine if you will need a high-low adapter to keep the bars within 3" of level. The baseplate will have a height of 16-1/4" on stock tires. We have adapters like the 4" # RM-048-4 if your...

  • Why are The Roadmaster Smart Diodes Required For a 2022 Jeep Wrangler 4xe?
    If your 2022 Jeep Wrangler 4xe has the ParkSense proximity sensors you will need either the Wiring Kit 152789 # RM47ZR or the Smart Diodes # RO54FR. If you already have an entire wiring kit you can replace the standard diodes with the smart diodes. The diodes allow the variable voltage tail lights to operate at the correct voltage.

    First you will need either the Base Plate # RM79RR for the factory plastic bumper or the Base Plate # RM92ZR if you have the Ford Modular front bumper. I recommend using the Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar # RM-676 as the arm bodies have an aluminum construction to help resist corrosion. It also has built in LED lights which make it much easier to connect or disconnect in the dark. You may need a High-Low adapter like the 4" # RM-048-4 to keep the bars within 3" of...

  • Troubleshooting Error Message with Wiring Diode Kit Installed on 2021 Jeep Gladiator with LED Lights
    There are 2 possible reasons why your install of the Flexo-Coil Wiring Kit # RM-15267 is causing an error to pop up on your 2021 Jeep Gladiator; the first is that something was installed incorrectly, and the second is that you have the ParkSense on your Gladiator and you need special diodes.

If you jump to about the 7:00 minute mark you'll see how we make our connections with the...

  • Can You Reuse A Demco Stay-In-Play Duo From A Jeep Wrangler In A Ford Bronco
    The diodes required for your 2022 Ford Bronco will depend on whether or not you have variable voltage lighting. For LED's you'd need to use part # RO54FR and for Incandescent bulbs you'll need part # RO34FR. If you wanted to get them as a kit including the 4-pole wiring and 7-to-6 pin cable then you'd want part # RM26FR for Incandescent and part # RM38FR for LED's. If you do not have variable voltage wiring then you'll be able to use the standard diodes that you ordered. For the Brake...

    Variable voltage tail lights use the same wire for the brake signal and running lights instead of the standard turn/brake wire setup. To determine if you have variable voltage tail lights you'll need to pull the tail light out to get to the wiring and test wires with a probe tester # PTW2993 in order to see if the same wire powers both the running lights and brakes. If you do have variable voltage LED tail lights then you'll need the Roadmaster Smart Diode 7-Wire to 6-Wire Wiring Kit...

  • How To Power A Third Brake Light With Diode Wiring While Flat Towing
    The reason the third brake light isn't coming on is because the Roadmaster Wiring Kit with Smart Diodes for Variable Voltage LED Tail Lights # RM47ZR is only being wired to the just the tail lights. To get the third brake light to activate you would need to splice in a jumper wire between the third brake light and the the "RV Brake In" on the diode. You would need an additional Smart Diode # RO54FR for the third brake light and essentially wire it the same as one of your tail lights....

  • Is Lower Voltage Output Expected From RV Taillight Input
    According to Roadmaster, the 1.8V reading is in the acceptable range on your # RO54FR. The smart diode has built in resistors which take the voltage down low like that. It gets especially low for the LED version since it takes very little to power an LED light. Once you install it on your vehicle you will find that everything works as intended.

  • Can Regular Hy-Power Diodes Be Used On Constant Voltage LED Lights
    Yes, the standard diodes like the Roadmaster Hy-Power Diode # RM-790 will work with constant voltage LED lights. The Roadmaster Smart Diodes for Variable Voltage LED Tail Lights # RO54FR you were looking at are designed for use on variable voltage LED tail lights, which on typically found in Jeeps with ParkSense Proximity Sensors. If you provide me with the year/make/model of the vehicle you're wanting to flat tow I'd be happy to find the correct components to get you out on the road.

    You can mount the Putco Blade LED Tailgate Light Bar # P72KR on your 2021 GMC Canyon with the included wiring kit. The light bar would only be able to be used as a 3rd brake light when used in the flat tow setup. As the wiring ties the bar directly into the 7-way connector on your Canyon you will need to have an additional Diode from the Set # RO54FR for the light bar. This diode will wire in but first you will also need a 3rd Brake Light Logic Module # PP20-702 to separate the turn signals...

  • Smart Diodes and Wire For Flat Towing Vehicle Behind Motorhome
    We do indeed offer smart diodes in two models, if the vehicle has incandescent lamps, use # RO34FR or part # RO54FR for vehicles with LED lamps. All the 7 to 6-way umbilicals we offer like # RM-146 use 16 gauge wire, however the # RM-146 meets the rest of your parameters, it's manufactured in the USA and has metal plugs on the ends. Unfortunately we don't offer bonded 4 wire in 14 gauge, although we do offer it in 16 gauge as part # 16-4B-1, which is sold by the foot.
