Roadmaster Tow Bar Wiring - RM-152
- Diode Kit
- Splices into Vehicle Wiring
- Tail Light Mount
- Universal
- Roadmaster
Diode kit allows you to use your vehicle's tail lights and wiring system while preventing feedback from your RV. Wires 2-wire and 3-wire systems to operate as a combined lighting systems. Connectors and Extension loop sold separately.
Features:
- Lets you wire your vehicle to accept your RV's tail, brake, and turn signal lights for flat towing
- Wires towed car as combined system so that brake and turn signals travel along same wire
- Prevents electrical feedback and the damage it can cause to your vehicle's electrical components
- Aluminum case protects diodes from the elements
- Powder coated aluminum is corrosion resistant
- Includes 4 Hy-Power diodes; 30' long, 4-wire harness; wire connectors; cable ties; 1 ring terminal; and 3' long plastic loom
- Extension loop for connecting towed car to RV is sold separately
- Brake light relay (RM-88400 - sold separately) may be required if used with supplemental braking system
- Limited Lifetime Warranty
Specs:
- Max amperage: 85 amps
- Max voltage: 24 volts
Note: For applications that have separate lighting, this kit will cause your brake lights to function as both brake and turn signal lights. A wiring converter (118158 - sold separately) and 2 additional diodes will be needed if you want to retain separate turn and brake signals.
Separate vs. Combined Lighting Systems
Some automobiles operate on a 3-wire system, wherein the brake signal and the turn signals travel along different wires to illuminate different lights. (Typically, these vehicles have amber turn signals.) This is referred to as a "separate lighting system". When you hook up for flat towing using this kit, your towed car's lighting system will operate in a combined fashion regardless of whether it typically has combined or separate lighting. This means that the brake and turn signals sent by your RV to your towed car will be carried on a single wire. As a result, your car's brake lights will do the flashing for the turn signals. Your vehicle will still function as designed when not hooked up to your RV.
Do You Need a Brake Light Relay?
Because this kit wires your vehicle as a combined system, a brake light relay (RM-88400 - sold separately) may be required if you use a supplemental braking system with your towing setup. A supplemental braking system depresses the brake pedal in your towed car every time you apply the brakes in your RV. So, if your towed car's brake lights illuminate when the brake pedal is pressed and the engine is off - as is the case when towing - then you need to install a relay to ensure that the lights on your towed car always act in accordance with the signals sent by your RV via the wiring harness. Without a relay, the brake signal from your towed car will override the turn signal sent by your RV when you slow down to make turns, creating a potential hazard.

have successfully completed the installation of the following items that I purchased from etrailer:
> Nighthawk RM-676 tow bar
> RM-524458-5 base plate
> DEMCO Stay in play DM86VR
> RM-152 diode wiring kit
> RM-156-25 charge wire kit
> RM-88400 brake switch relay kit
I work slow but methodically. I had no issues other than the high degree of difficulty for a 68 y/o man working alone. This project exceeds the abilities of someone NOT mechanically inclined. There is also the need for some specialty tools. I found that feeding the wiring through the dash, firewall, and underbody was more difficult than installing the front baseplate. Overall, I am satisfied with the function of this installation. I am glad I did it myself rather than having it done.

I have no regrets with this purchase. Items preform as advertised with no issues. I am very satisfied with Roadmaster and Demco products.
Jeffrey - 11/19/2022by: Dan05/21/2023
Product quality was not a issue. However the instructions for hooking car to rv was to place the power cord below the safety cables. This resulted in damage by dragging. Had to purchase a new cord now place it on top of safety cables. NO more issues.

Negative battery disconnect system started not working after less than a year
Had to go to local Chevy Dealer to have the battery disconnect system disconnected as was causing whole electrical system to shut down at inadvertent times
Comments
The wiring kit does have a limited lifetime warranty and I wanted to ask if you have reached out to Roadmaster?

We just came back from fmca show in Perry ga and I can’t say enough about roadmaster they came by our motorhome and inspect the hitch and oiled and left us a note that it was good shape.
Let me say 1 more thing don’t let camping world install it on your car they did our 1st car and they installed it wrong and never worked right or couldn’t get it unhooked without a hammer and pin
by: William02/14/2023
Installed a Blue Ox Base Plate kit on a 2015 Cadillac SRX. The base plate arrived promptly and was well packaged considering its weight. Watched the videos etrailer provides and used them as a step by step video guide. The videos were a big help. Installation is not too difficult if you're mechanically inclined. Had someone help with the installation but one person can perform the installation. I think the base plate is well engineered and everything fit as it should. Love the fact the installation is so well hidden. We have about 400 miles on the installation and have had no issues. Thanks to etrailer for a great price, great service, and great product support.
by: Steve C03/03/2019
Just finished installing the “kit”, everything went well, the video on the etrailer web site helped but was slightly different than my installation since it was a 2006 model and mine is a 2012.
Should make towing and hooking/unhooking easier and safer than using the magnetic lights.
I’m using the Pollack 6 pin connector with the wiring “kit”.

Works Great, Totally Transparent During Towing or Normal Use
Steve C - 03/04/2020by: Charlie04/09/2023
The videos were very helpful as it was the first time assembling the tow package. Probably took me about 20 hours in total. The videos sure make it look easy. Drilling the holes into the frame, for the bolts was probably the hardest thing. Make sure you use the permanent lock-tight, they will vibrate loose! Thanks for all the helpful videos. Tow package works great.
by: Ray04/25/2023
Upgraded to a new tow vehicle and etrailer had all of the components that I needed. I was working with a short timeframe to get the new vehicle adapted before hitting the road for the summer. All parts were delivered promptly and with no damages or missing parts.
by: Ralph06/14/2023
Produce was well described and arrived on time with clear installation instructions.
by: Bill 04/04/2023
If you want knowledge people who know what they are doing all you have to do is call e-trailer!
This is what I needed as a final step in getting on the road with my truck in tow! I have talked with more than a few parts providers, including Blue Ox, trying to get this project done. None of them came in even a distant second!
by: Ellen M01/14/2023
We purchased a used motorhome that had the Blue Ox Towing as well as the Patriot Brake system. We needed to order the tow plate for our toad as well as a few other items to get the set up ready. Kim was amazing at helping me get all of the parts needed to get us rolling! etrailer is the BEST!
by: Ron 05/27/2023
An easy install (if you watch the video), with quality products. Works like a charm!! The price and service was excellent!
by: Greg10/05/2022
The diode kit wiring kit was about 5 feet too short on a 2014 CRV one of the the shorter SUV one could pull. Had to get another trailer wiring kit to chop apart to splice a longer section in. How much would it have cost to add 5 feet of wire? Wasted time and money!
by: Rick 08/26/2023
No problems. Did exactly what I needed!
by: William 09/09/2023
Excellent service, knowledgeable and patient. Quick delivery, All excellent!

Durable and well constructed, you know when it is connected.
by: Bill 07/08/2022
It is so easy to work with eTrailer!! A couple of phone calls and all your questions are answered. Their videos are also spot on and helped me tremendously when the place that installed the base plate said that they wouldn't install the BRK2505 brake breakaway kit. A simple view of their video and i was confident I would be able to tackle this portion of the install. thanks eTrailer, GREAT JOB!!
by: William06/08/2022
Hey George, just dropping a short line to let you and etrailer know that I'm definitely satisfied with your products. I'm using both the diode wiring kit and front tow hitch to tow behind the motorhome. Both have worked well over the past year. Your online videos were also a great help in understanding how and why your products work. I look forward to reaching out to etrailer again if/when I need additional upgrades to my Jeep.
by: Brian 04/02/2023
This is the ticket.works great. With your online videos. I was able to do it all myself.
by: Mark 05/12/2023
Product arrived as promised - thank you for the live help on the parts needed,
by: Josh01/26/2022
After one year, one of the components installed in my truck's rear tail light was fried making my tail lights not work (even when not being towed). I called etrailer and told them the situation. JT was very helpful in setting up an appointment and getting the part fixed (under warranty). Slight annoyance followed up with good customer service.
by: Robert03/22/2023
Worked perfectly
by: Richard02/12/2023
Gwen was extremely helpful and pleasant and I am sure I'll be back next time I need something for the RV.
by: daveg09/08/2020
This review is for E-Trailer. I ordered a complete dinghy towing set-up for the dinghy as a towbar came with the RV we purchased. I called E-Trailer and spoke with a very knowledgeable young lady and when I told her what I needed in layman’s terms she came up with what I would need to complete the dinghy preparation in order to safely tow it behind our RV. Everything they said it would do went just as the instructions directed. I ordered a Roadmaster Falcon 2 set up for the dinghy and they suggested a Blue Ox self contained braking system for the SUV itself. hey also suggested the complete wiring system and plug for the dinghy. To my amazement after the RV and dinghy were connected that also was as easy as they said it would be. Our first tow with the dinghy was great and the unhooking was also a very easy experience. This company was awesome to work with. Thank you for your knowledge and great products.

- Is There An Installation Video of the Roadmaster Bulb and Socket Kit on a 2017 Ford F-350At this time we do not currently have a video of the installation process of the Roadmaster # RM-152-LED kit on a 2017 Ford F-350, but as soon as we do get an opportunity to make one we will certainly be looking to take advantage. To install a Roadmaster Bulb kit like the # RM-152-LED you'll need to remove the tail light housing on your vehicle and just choose the best spot for a 1" hole to be drilled without interfering with any of the other lights or wiring components. You could potentially...
view full answer... - What Color Are the LEDs That Come With the Roadmaster Tail Light Wiring Kit for Towed VehiclesThe Roadmaster Tail Light Wiring Kit for Towed Vehicles part # RM-152-LED comes with red LEDs which are needed because with LEDs you must use a bulb color that matches that of the tail light housing in order to get a true color. The bulb type that is used is indeed an 1157 so there would be different intensities based on if the stop or tail lights were activated. Please note, the Replacement LED Bulbs and Sockets part # RM-152-2 are just the replacement LEDs for the Roadmaster Tail Light...
view full answer... - Troubleshooting Brake Light Failures When Flat Towing A 2019 Buick EnvisionThe Roadmaster Even Brake Portable Supplemental Braking System # RM-9400 wouldn't affect your brake lights in that manner. You most likely have a short or loose connection in the tow bar wiring which is causing the turn signal to work but not the brake light. You'll need to check all of the wiring running from the tail lights to the 4 or 6 wire port you have on the front of your 2019 Buick Envision for any shorts, kinks, or brakes in the wires or a complete disconnection of any wires.

view full answer... - Replacement LED Bulb and Socket for Blue Ox Tail Light Wiring Kit for Towed VehiclesYes, although not the brand you requested we do offer just the bulb and socket that comes with the tail light wiring kits and it can be obtained using the Replacement Bulbs and Sockets part # RM-152-2 which has LEDs. The wire colors may not be the same but you can still use these in place of the ones that come with Blue Ox kits.

The bulbs in this kit are designed to be placed in your tail light housing next to your vehicle's bulbs and the wiring run to the 6-wire port at the front of your vehicle to connect to your RV with. If you're meaning that you want to replace the bulbs in your vehicle then no, you would not be able to use the # RM-152-LED...
view full answer... - Adding Tow Bar Wiring to 2018 Toyota Camry Being Towed on a DollyYou can add lights to your Camry that is on a tow dolly, but there isn't a conversion kit or anything of the sort. The only thing that you can do is add tow bar wiring such as the Roadmaster Universal Hy-Power Diode Wiring Kit # RM-152, cutting off the 4-way from the tow dolly and connecting all of the wires inside a junction box like # 38656. I have added links below to some video reviews of these parts for you to check out as well if you'd like.
view full answer... - Can Diode Tow Bar Wiring Install on Vehicle with T-One Trailer WiringSince the Tekonsha trailer wiring kit part # 118727 installs between the taillight connector and the factory wiring you'd install your diode kit tow bar wiring like part # RM-152 on the factory taillight wiring and it would not interfere with operation of the trailer wiring.
view full answer... - Will Roadmaster LED Tail Light Bulb and Socket Wiring Kit Work with Incandescent Bulbs on an RVYes, but, your RV likely has a trailer connector on it already and that connector is not tied into the RV tail light wiring so it would not affect Roadmaster Tail Light Wiring Kit for Towed Vehicles - LED Bulb and Socket - Red Item # RM-152-LED. Even if the RV did have a connector that was spliced into the tail light wiring on the RV this kit would still work for you! I have included a link to a video showing an example installation on a 2017 Chevy Spark.
view full answer... - Tow Bar Lighting Kit Recommendation for 2006 Saturn VueWe checked with Roadmaster and the LED bulb and socket kit you like part # RM-152-LED is a confirmed fit and will work great! We actually had the chance to install this kit on a similar 2007 Saturn Vue that I attached an install video that covers.
view full answer... - Will the Roadmaster Tail Light Wiring Kit # RM-152-LED Provide All Lighting FunctionsYes, the Roadmaster Tail Light Wiring Kit for Towed Vehicles, # RM-152-LED, will operate tail, stop, and turn signals with one LED blub per side of the vehicle.
view full answer... - Is There a Specific Location to Install the Wiring Kit # RM-152-LED on a 2017 GMC Sierra 1500The 1" hole for the Roadmaster Tail Light Wiring Kit # RM-152-LED isn't actually very specific. Just as long as you have enough room for the LED bulb. I wish I could be a little more specific but we have never installed this kit on a 2017 GMC Sierra 1500 ourselves (as of Sept 2018) so we don't have an exact video to reference and the installation instructions are very generic. I have linked installation videos on a 2016 GMC Terrain and a 2003 Toyota Tacoma so you can get an idea of where...
view full answer... - Diode lighting Kit Needed For Flat Towing A 2020 Jeep Gladiator With LED LightsSince you have LED tail lights the Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 7-Wire to 6-Wire Straight Cord Item # RM-152-98146-7 will not work. Instead you'll need the Roadmaster Tail Light Wiring Kit w/ 7-Way to 6-Wire Connector - LED Bulb and Socket - Red Item # RM-152-LED-7.

The Roadmaster 4-Diode Universal Wiring Kit # RM-152-98146-7 comes with a straight cord while the Roadmaster 4-Diode Universal Wiring Kit # RM-152-1676-7 comes with a "hybrid" cord that is straight on one end and coiled on the other. I prefer the coiled option as it helps to keep the wiring above the ground easier. The only time a straight cord is better is if the tow bar has channels to route the wiring through. For a...
view full answer... - Which Diode Tow Bar Wiring Kit to Use When Already Have Coiled 7 Way to 6 WaySince you already have a coiled 7-way to 6-way adapter the diode kit part numbers you would want are part # RM-152 for the diodes and wiring for the towed vehicle side and then for the 6-way socket to mount on the front of your vehicle # RM-910030-7 and you'd be set.
view full answer... - Is Brake Lite Relay Needed When Installing Bulb and Socket Kit on 2009 Ford Escape HybridYes, since your braking system presses the brake pedal of your 2009 Ford Escape and the brake lights come one with the ignition off you need to use a brake lite relay part # RM-88400 so that the LED bulb and socket kit part # RM-152-LED turn signals will still work when the brakes are applied.
view full answer... - Diode Kit and 6-way Plug Without Coiled Adapter For Towed VehicleYes, if you do not need the 7-way to 6-way coiled adapter cord you can purchase Diode Kit and wiring part # RM-152 and trailer side 6-way plug part # RM-910030-6. The Diode kit part # RM-152 comes with 4 diodes and 30 feet of 4-wire. It also comes with the connectors, zip ties, 1 ring terminal and plastic loom to wire the vehicle for lights while flat towing. I have attached an installation video of the diode kit in a 2005 Chevrolet Avalanche. The 6-way plug part # RM-910030-6 is...

This will allow you to use the existing wires that you've already run with the Roadmaster Tail Light Wiring Kit # RM-155 and add LED tail lights in the place of the incandescent bulbs.
view full answer... - Bulb and Socket Kit for Flat Towing that Uses LED BulbsThere is an LED bulb and socket that you can use for flat towing. It is # RM-152-LED. The LEDs are red which work better than white lights if behind a red lens. I have linked a video showing an example installation for you.

The only way to get lights up front would be to use a tow bar like the Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar # RM-676, which comes with built in LED lights along the arms to help alert other drivers of your presence on the road. If you're just wanting to replace the side marker lights with something brighter then there are kits available,...
view full answer... - Tow Bar Wiring Recommendation for 2016 Ford F-150 with Backup Sensors in TaillightsYou can certainly use diodes, as you referenced, to install towed vehicle wiring on your customer's vehicle. To wire the 2016 Ford F-150 with the back-up sensors in the taillights I recommend using a Roadmaster Diode Kit, like the Roadmaster Diode 7-Wire to 4-Wire Flexo-Coil Wiring Kit # RM-15247. I confirmed with my contact at Roadmaster that the diode kits will not interfere with the sensors in the taillights. This kit includes the 4 diodes needed to wire the taillights for use while...

Without seeing your tail light assembly fully taken apart to know where you'll have enough clearance in the red portion of the lights it's hard to say a specific spot will work. The LED bulb is going to stick into the light assembly 2" so as long as you have that amount of space it should be fine.
