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:
Specs:
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.

Connectors and Extension loop sold separately.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.

It fits the bill--when they say universal that's correct; may not be a "factory" wiring harness but our Super Beetle is 45 yrs old.
I think that the diodes need pig tails that could be soldered and sealed with shrink tube.
I don’t want to think about the salt, mud and water eating away at the exposed connections.
Make running tail light power from your tow vehicle to your flat tow vehicle easy.
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
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

The wiring kit does have a limited lifetime warranty and I wanted to ask if you have reached out to Roadmaster?
Everything works for the braking system. Very easy to hookup.
etrailer always has what you need with competitive prices.

Seems to be working fine.
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.
Haven’t hooked up yet but they were very helpful and easy to deal with.
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
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.
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.
Very easy install
Produce was well described and arrived on time with clear installation instructions.
The kit was fine. We couldn’t use it on our truck.
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!
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.
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!
Great product. Worked perfectly.
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!
An easy install (if you watch the video), with quality products. Works like a charm!! The price and service was excellent!
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.
