Roadmaster Flat Tow Wiring Harness - RM-152-98146-7

  • Diode Kit
  • Splices into Vehicle Wiring
  • Universal
  • Roadmaster
  • Tail Light Mount

This complete kit includes everything you need to carry your RV's brake and turn signals to your towed car's tail lights. Diodes prevent electrical feedback. The straight 7-to-6-wire adapter cord is ideal for tow bars with channel guides.


Features:

  • Carries your RV's tail, brake, and turn signals to your towed car
  • Prevents feedback that can damage your car's electrical components
  • Runs power from RV to towed car with 7-way to 6-way adapter cord
    • Straight cable is ideal for tow bars with channel guides, such as Roadmaster all-terrain tow bars
    • 6-Way socket wires to harness and mounts on front of towed car with included bracket
  • Includes:
    • 4 Hy-Power diodes
    • 4-Wire harness
    • 7-Way to 6-way adapter cord
    • 6-Way socket with mounting bracket
    • Butt connector, ring terminal, zip ties, and wire loom
  • Limited lifetime warranty


Specs:

  • Maximum amperage: 85 amps
  • Maximum voltage: 24 volts
  • Adapter cord: 6-1/2' long
    • Wire gauge: 16
  • Wiring harness: 30' long
  • Plastic loom: 3' long


Notes:

  • A brake light relay (RM-88400 - sold separately) may be required if used with a flat tow brake system. (See below.)
  • A wiring converter (118158 - sold separately) and 2 additional diodes will be needed to retain separate turn and brake signals. (See below.)

Combined Lighting System vs Separate Lighting System

Combined vs Seperate Lighting System

A combined lighting system, or 2-wire system, uses the same light bulb to signal both braking and turning. (In other words, the car signals a turn by flashing the brake light.)


A separate lighting system, or 3-wire system, has the brake signal and the turn signal light up independently of each other. Typically, the turn signal is amber.


To keep the separate lighting system on your car functioning properly while you're flat towing, add a wiring converter (118158 - sold separately) and 2 additional diodes.


Do I Need a Brake Light Relay?

If the engine is off and your car's brake lights illuminate when you press the brake pedal, you need to install a brake light relay (RM-88400 - sold separately) with this kit. Without a relay, your car's brake signal will override the turn signal sent by the RV when you are slowing down to make a turn, creating a potentially dangerous situation. Other drivers will see that you're slowing down, but not that you're making a turn. With a brake light relay, you can signal both and travel safely.

  • Differences Between the Demco & Roadmaster Base Plate Kit for a 2024 Ford Maverick
    The main difference between the Demco Tabless Base Plate Kit # DM77YV and the Roadmaster Direct-Connect Base Plate Kit # RM97RR is just going to be the brand really. They're both very similar in the way they install, with Roadmaster being a bit more challenging requiring some trimming on certain models, they both have a removable drawbar, and they both use a direct connect style attachment. If it were me I'd go Roadmaster just for the fact that they've been consistently a household...

  • Complete Flat Towing Setup For A 2018 Ford Expedition Limited
    Sure thing! To complete your flat tow setup for your 2018 Ford Expedition, you will also need: 1. A base plate kit, like the Roadmaster Direct-Connect Base Plate Kit # RM-524457-5. You'll need a base plate kit to connect your tow bars to your toad vehicle. 2.The next thing you're going to need is a braking system, like the Roadmaster BrakeMaster System w BrakeAway for RVs w Air or Air Over Hydraulic Brakes # RM-9160, with the RoadMaster BrakeMaster Custom Seat Adapter # RM-88318.

  • What Base Plate Can I Use with My Blue Ox Acclaim or Adventurer Towbar on My 2022 Jeep Wrangler?
    I have a great base plate solution for you. Since you say that your Blue Ox tow bar has a 5k capacity, I believe you are referring to either the Blue Ox Adventurer Tow Bar - Car Mount - 2" Ball # BX7322 or the Blue Ox Acclaim # BX4330. Unfortunately, we do not currently carry an etrailer baseplate that can be used with either of these models. However, we have a great Roadmaster base plate and adapter that will allow you to use your tow bars on your 2022 Jeep Wrangler. For that setup, I...

  • Parts Needed to Flat Tow 2020 Chevy Silverado 1500 Diesel
    I checked with Blue Ox and the # BLU54VR that you referenced does not have fit exclusions for the diesel engine versions of the 2020 Chevy Silverado 1500 so it would work great for your truck. The Avail Tow Bar part # BX7420 would be a great solution as well. The battery of your truck does need to be disconnected when flat towing it which is why the Roadmaster quick disconnect kit part # RM-766 is recommended as it makes this easier. Your current braking system would work great. For lighting...

  • Does Base Plate Fit 2021 Nissan Frontier With Automatic Transmission
    It does; the "Manual Transmission" spec on the page is due to the fact that only the manual transmission for your 2021 Nissan Frontier can be flat towed, unless you get a drive shaft disconnect like you are. But the transmission does not affect the fit of the base plates, so they will work on your '21 Frontier. Along with the base plates there are a number of other parts you'll need, which I'll go ahead and list out for you: - Base Plate Kit: Roadmaster Direct-Connect Base Plate Kit #...

  • Troubleshooting a Flat Tow Wiring Harness Not Working When Changing RVs
    Thanks for all the information Les and congrats on your new motorhome. You've definitely narrowed the problem down. Have you checked the 7-Way connector on your new 2025 LTV Unity? From what you're describing it sounds like it is not functioning correctly. It could be missing a fuse/s, a ground, or it might not even be getting power. I recommend checking your RV's 7-way connector with a circuit tester like # PTW2993. You'll need to have a friend sit in the RV and perform each of the connectors...

  • Parts Needed to Flat Tow 2013 Jeep Wrangler with Off Road Bumper
    For a base plate kit tow tow your 2013 Jeep Wrangler that has an off road bumper with 1 inch D-rings you'd need to start with the # BX88358 for a Blue Ox setup. Then for a tow bar you'd want the # BX7420 which is the easiest to use and allows the vehicle to track the best behind the coach. For lighting you'd want the # RM-152-98146-7. The diode kit that comes with this allows you to splice into the taillight wiring so that your RV controls the vehicle taillights and does not require drilling...

  • D Ring Tow Bar Adapters And Flat Tow Setup For 2017 Jeep Wrangler
    Great question. The only adapter we have that will work with a Ready Brute is the Blue Ox Base Plate Adapter Brackets for Ready Brute Elite Tow Bars # BX88297. This adapter, will work with the tow bar but won't work with the D-rings. You would need a blue ox base plate. For me to get you the proper base plate I would need more information about your bumper and some pics of it. We have two sizes of D-ring adapters 1 inch and 3/4 inch. Two examples of this would be the Adapter for Jeep...

  • How to Tow a 2019 Jeep Cherokee Behind a Motorhome
    You can flat tow the 2019 Jeep Cherokee if it is a 4x4 model with 2-speed power transfer unit. Models with the 1-speed power transfer unit would have to be put on a trailer. None of the 2-wheel drive models can be flat towed but you can dolly tow front wheel drive models from the front. If you do have a model that can be flat towed and it is a Trailhawk or Overland edition you can use base plates # RM-521451-5. For a compatible tow bar I recommend the Falcon All-Terrain # RM-522.

  • What Flat-Tow Setup do You Recommend for My 2014 Jeep Wrangler Unlimited with Standard Bumper?
    For flat-towing your 2014 Jeep Wrangler with a factory standard bumper, you need a base plate, a tow bar, a tow braking system, safety cables, and vehicle tow wiring. For those parts, I recommend the following: - etrailer Invisible Base Plate Kit - Removable Arms # e98949 (non Rubicon-X models only) - Blue Ox Avail Non-Binding Tow Bar - Motorhome Mount - 2" Hitch # BX7420 (comes with safety cables) - Brake Buddy Select 3 Portable Supplemental Braking System # HM39524 - Roadmaster 4-Diode...

  • Base Plate RM67VR VS RM77VR Comparison And Compatibility With RM-422 Tow Bar
    Both Item # RM77VR and Item # RM67VR are the same cross-bar style base plate but with different connection arms so installation will be the exact same for both. Since you're using the Roadmaster BlackHawk 2 All Terrain, Non-Binding Tow Bar - Motorhome Mount - 2" Hitch - 10K Item # RM-422 both base plates will work with this tow bar but the RM67VR will be slightly less time to connect because the # RM-422 comes with the same connection plates already installed.

    Yes your 2011 Kia Sorento with a manual transmission can be flat towed. You'd need a base plate confirmed as a fit for your vehicle like with the Blue Ox part # BX2719. Then for a tow bar the # BX7420 is very easy to connect/disconnect from and also allows the vehicle to track better behind the tow vehicle than other options. Then for wiring/lighting the part # RM-152-98146-7 would work great as a way to control the taillights of the tow vehicle due to the diodes that install on the...

    We'd be happy to help with that. As long as your Colorado has a transfer case that has a Neutral and a 4 wheel low position, it can indeed be flat towed. For base plates, I'd recommend the Roadmaster Direct Connect base plate kit, part # RM78VR which Roadmaster confirms is compatible with the ZR2 package. For a tow bar, I'd recommend the Roadmaster Falcon All-Terrain tow bar, part # RM-522. You'll also need # RM-643 safety cables. To wire the taillights, use the # RM-152-98146-7 diode...

    The only difference between the (now discontinued) Roadmaster Crossbar-Style Base Plate 1419-5 and (now discontinued) Direct-Connect Base Plate 1419-6 for your 2000 Jeep Grand Cherokee is that the crossbar style requires a separate piece to attach the tow bar, the Crossbar Assembly for Roadmaster Motorhome Mounted Tow Bars # 910021-00. Because they are discontinued I recommend going with a base plate from Demco that fits your Grand Cherokee, along with a compatible tow bar: - Demco Classic...
