2010 Hummer H3 - Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit
- Diode Kit
- Splices into Vehicle Wiring
- Tail Light Mount
- Universal
- Roadmaster
Diode kit allows you to use your Hummer H3'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. Includes 7-wire to 6-wire Flexo-Coil electrical cord.
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
- Diodes powder coated aluminum case is corrosion resistant and provides protection from the elements
- Brake light relay (RM-88400 - sold separately) may be required if used with supplemental braking system
- Flexo-Coil cord is resitant to water, oil, chemicals, and has silicone-injected plugs to prevent corrosion
- Center pin on 6-Way plug wired to 12V power, there are two industry standards
- Includes:
- 4 Hy-Power diodes
- 4-Wire harness
- 27" Long
- Wire connectors
- Cable ties
- 1 Ring terminal
- 3' Long plastic loom
- 8' Coiled cord
- Vehicle mounting bracket
- Socket
- Made in the USA
- Limited Lifetime Warranty
Specs:
- Diode Max amperage: 85 amps
- Diode Max voltage: 24 volts
- Coiled cord max length: 8'
- Coiled cord retracted length: 15"
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 (RM-792) 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.

Very complete kit. My only problem mounting it in a 2014 Chevy Spark is the limited space for the diodes. After much trial and fitting I found a suitable location. See photo.
by: Ken05/17/2024
This item was recommended by Jameson once he saw what I was planning to order for the tow bars and brake system. It was installed by a shop on the etrailer authorized installers list, along with everything else for the entire towing system. It does attach to both vehicles just fine, although at first I wasn't sure it was fully attached on the motorhome side. I was afraid it would just slide back out, but it hasn't.

GMC Sierra
The wiring kit does what it is supposed to do. I would like to see all of the terminal connections to be the marine grade heat shrink type with the solder inside. The type that join the wires with a heat-gun. I installed this in a 2024 GMC Sierra Denali 1500. I chose to mount the connector by drilling an hole through the plastic front license plate. This will be covered with a flip-up license plate frame. All-in-all, I would purchase this set again.

Finished wiring and first effort to plug in red flex coil to the Jeep and the outside protection cover broke apart; very disappointing. Trying to contact Etrailer for replacement.

Toyota Tacoma
2018 Toyota Tacoma TRD Sport 4x4 install, summer of 2023. This was simple to install. Easy to run along the underside of the truck and snake up into the taillights. Plenty of wire and worked fine when complete.
by: Gary04/12/2024
Haven't installed it yet, but the kit seems to include everything I need. My contact at etrailer did a great job of getting me exactly the right parts to complete my flat tow package, and the videos available on the web site to help with installation are a great feature. I don't think I would tackle this installation myself without all of the helpful information these folks provide.

This seemed unnecessary but is really the only proper solution when working with LED taillights. It works perfectly.

Jeep Wrangler
I've used this setup for a year towing a 2023 Jeep Wrangler . I 100% recommend it for anyone else. Under normal conditions it is very easy. Under stressful conditions (bad weather, uneven terrain, need to connect/disconnect quickly) it is a life saver.
I am 63 and I can connect/disconnect this in 5 minutes.
by: John05/17/2024
This kit worked out well. It contained everything needed to tap into my vehicles lights and continues to be trouble free after a year of use.
by: Bob05/23/2024
Worked fantastic.. after I received it I installed it and went from indiana out west. I have put around 9 thousand miles on it so far.
by: Dan 02/10/2024
I have to say : E trailer always delivers !
This is exactly what ya need if you are adding a second vehicle or swapping your old system to a new rig. I could have gotten by without the plug but for the price decided I should get a spare.
Delivery was prompt and product was exactly as described.

2011 Jeep Wrangler
We added this kit and tow cable to keep our Jeep battery charged while towing, so the supplemental brake could stay powered. It has worked well for us for several long trips from GA to NH and MI. The Jeep side of the tow cable ended up with a crack in the metal plug, but we were able to get a replacement plug and rewire it pretty easily. We are going to complete the wiring for the tail lights before our next trip.
by: roparv03/06/2023
Installed as per video...I had a local car/truck accessory shop install mind as way too many facial screws for me to content with. $400 to have it done right.
(A little worried that if I get too close to a vehicle or wall that some damage my occur as cable connector and braking wiring sticks out 3-4 inches from front of car.) My older system was cleaner design across the front of the car.
by: Gary12/06/2023
My Roadmaster Sterling tow bar has a channel for the wiring kit to run through. the coiled wire is not easy to work with on this bar if you want it to run through the channel. 10 months into using it the 6 wire end disintegrated and had to be replaced. luckily we were camped right beside a Camping World.

The video instructions made this harness very easy to install (other than routing the wire to the back of the Jeep). Everything functions as it should. I'm very happy I went with this harness versus magnetic lighting.

A bit of a learning curve for first time dyi on this type of thing. Key is to make sure you figure out what type of brake light systems you have. There are 2 types and 2 different wiring diagrams. Read directions thoroughly. Works well. 2009 dodge 2500 install

Just wanted everyone to know, that after one year of owning and using the Roadmaster towing baseplate, and the wiring harness for my 2022 Ford Maverick, I have accumulated over 10,000 miles of trouble free towing behind my Motorhome. The folks at etrailer did a great job making sure I had the right parts and at a good price. Delivery of the parts was exactly the day it was promised. I highly recommend them when need these kind of parts. I really appreciated the great and friendly service!! Safe travels

Still working fine.
by: Timothy02/15/2024
Works good. Reasonably easy to install. The diodes are large and you have to get them 'just so' behind the tail lamp assemblies to get the lights to seat properly.
by: Skid Lid01/24/2024
Project went as expected. I did purchase additional split loom from Harbor Freight to protect the wires from the front to the rear of my truck. It easily ran inside the frame rails!

- Vehicle Tow Bar Wiring for Flat Towing a 2015 Ford F-150I do have a solution for you, but we currently do not carry the Blue Ox BX88287 EZ Light Wiring Harness that you mentioned. To install a wiring kit on your 2015 Ford F-150 we do have the Roadmaster Universal Hy-Power Diode Wiring Kit # RM-154 which is similar to the Blue Ox BX88287 except that this option will need to be spliced in. I have attached a video of this being installed on a 2016 F-150 that you can reference. If your motorhome does not have the 4-Way flat connector that is on...
