2022 Ford F-150 - Roadmaster Universal Wiring Kit with Smart Diodes for Variable Voltage LED Tail Lights

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

The diodes in this kit convert the 12V signal from your RV to a 9V signal, ensuring that your car's variable voltage tail lights function as intended. 4-Wire harness included for installation. Adapter cord and plug sold separately.


Features:

  • Wiring kit lets you connect your RV's tail, brake, and turn signal lights to your towed car's lighting system
  • Smart diodes ensure that your variable voltage, LED tail lights function as they should while your car's being towed
    • Converts the 12V signal from your RV's wiring to a 9V signal so your tail lights work as intended
    • Prevents electrical feedback that can damage your vehicle's electrical components
  • Power coated aluminum casing on diodes is corrosion resistant and provides protection from the elements
  • Kit includes 2 smart diodes, wiring harness, split loom, ring terminals, and zip ties
  • Brake light relay (RM-88400 sold separately) may be required if used with supplemental braking system
  • Made in the USA


Specs:

  • Maximum amperage: 5 amps
  • Maximum voltage: 16 volts
  • Wiring harness length: 27'
  • Limited lifetime warranty


This 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 the 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 look and function as intended.


This wiring kit 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.


When installing this kit, you will need to add either a 4-way or 6-way round electrical connector to the front of your vehicle so you can connect to your RV when you're ready to tow. Use one of Roadmaster's coiled cable kits (RM-164-7 or RM-146-7 - sold separately) to get both the connector and the adapter cord needed for fast, easy hookup.


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 system works great. Installed on a 2023 Equinox LT (AWD). It was a little challenging running the wiring from the engine compartment to the taillights of the car, but not overly complex. The etrailer video is very helpful.

Only 3 feet of split loom and kit uses blinker lights as brakes.

After looking at the layout of a Chevy Equinox, you really would only need maybe a couple of feet of loom, Most of the wiring should be tucked up against the vehicle. As for the blinker lights, I need to know what model your Equinox is, in order for me to better assist you.

We were at a stand still. Wiring the lights from my motorhome to my ford pickup. Sheryl saved the day, without hesitation, she described just what we needed.

  • Do You Need to Run a 2021, 2022 or 2023 Chevrolet Equinox at Certain Times When Flat Towing
    Yes, the engine on your Chevrolet Equinox will need to be run at times when flat towing. The easiest way to determine what needs to be done to flat tow your Equinox is to consult your owners manual. I went ahead and took a look at the owners manual for both the 2021 and 2022 Chevrolet Equinox. For either model year, you will need to run the vehicle at the beginning of each day and at each RV fuel stop for about 5 minutes. This will ensure proper lubrication of the transmission components.

    We have just the thing! Most of the 2023 Bronco models will require use of a smart diode. It depends on what lighting system your Bronco has. If your vehicle has the variable voltage LED lighting you will want the # RO44FR. If it has incandescent lighting you will need the # RO94FR. The type of lighting will be specified in your owners manual. The Bronco LED lights look very different from the incandescent. The LEDs will have a clear lens with red behind, while the incandescent has a red/white...

For a complete flat tow arrangement for a 2022 Chevrolet Equinox, you will need a base plate kit, safety cables and a wiring solution to synchronize your RV’s lights to the Equinox. You will also need a supplemental braking system to synchronize your RV and towed vehicle's brakes. Once the selected...

The black powder coating is durable, and will blend nicely with the front of your vehicle. The twist lock arms are easily removable, so you will not have big metal pieces sticking out of the front of your car when not in use. This will be compatible with any Roadmaster brand tow bar.

You'll instead need the # RM-676 Nighthawk, which is compatible with Roadmaster Direct-Connect style baseplates.

These smart diodes are specifically designed to work with the LED tail lights on your F-150.

    Yes you are exactly right on how the Roadmaster Smart Diode Kit part # RO44FR will work on your 2019 Ford Edge ST. It will function the taillights of your 2019 Ford Edge like a combined setup where the stoplight and turn signal will be on the same bulb. This is by far the simplest and easiest way to wire up your vehicle and since it's just as functional as a separate setup I like it the most and would be what I would personally do if I were you.
