Wire your vehicle and get the signal lights required for flat towing without having to splice into your wiring with this custom, plug-in harness. Integrated diodes prevent feedback from RV for safe operation. Wires as combined lighting system.
Features:
Wiring your car for flat towing has never been easier. No more testing wires or splicing into your electrical system. No need to painstakingly position multiple diodes beneath your vehicle. No worries about voiding your warranty. With this custom-fit towed vehicle wiring kit from Hopkins, all you have to do is plug the harness into your vehicle's existing wiring, which is located at the rear of the vehicle. No cutting, tapping, or splicing is required.
After plugging in the wiring harness, use the included bracket to mount the 4-way flat connector at the front of your towed car. An extension loop (sold separately) is required to connect your towed car to your RV.
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 harness, 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.
Because this harness 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.

Kenneth - 02/09/2019Ford has at least three different electrical wiring plugs all about the same size, the picture really doesn’t show what is actually there! Try them all, once you find the right plug, all works fine! 551421
Product was easy to install and worked during testing, can't weight to get it on the road. 858530
Super easy to install. Arrived faster than expected. Would give it 5 stars if it was 3 wire or even if the 3 wire attachment was plug and play like this was. Love not having to splice into wires. 855653
Very good experience locating and ordering base plate and wiring harness etc. for my 2019 F150 that I'll be towing behind motor home. Everything was well packaged and delivered as promised. I recommend etrailer for your products. 814536
Installed per instruction had one minor question support from etrailer was prompt and excellent 804586
Made a tough task simple. No splicing wires, just plug it in and run the cable to the front. I wish the rest of the road setup was this simple. 786164
Even during a pandemic I received my order in a reasonable time frame. And better yet, it is all correct. Great selection and service. I will use etrailer.com again. 783261
Excellent product great factory like weatherproof connects. Plug & play hardest part was to run the wiring harness to the front of the vehicle. Which really was not hard at all, I would definitely recommend this product to anyone wanting to flat tow their vehicle. 769666
I just installed the wiring harness (HM56009). It was very easy, just plug and play. It only took about a half hour to install. 769476
Awesome kit. So much easier than having to remove taillight and splice into my F-150 wiring. Just plugs into existing wiring harness. 758858
Great products and fast delivery 749954
All; These folks are EXCELLENT!!! Great prices (better than other web stores in many cases) and their Customer Service is OUTSTANDING, seriously. My order was not huge but they were in constant contact with me, even on a Sunday!, letting me know where things stood and even following up after delivery to make sure I was happy... Where do you get that kind of service today?? I highly recommend etrailer.com. Great folks! 737443
Very easy to install but watch the video on the website, the connector is not as pictured or as located in the written directions that come with it. It literly took longer to run the wires along the frame rail and zip tie them to make the connections. I used the black 4 way holder and attached it to my bumper bit i don't like it, if i was to do it over i would just hide it behind the license plate. 2018 F150 XLT 4x4 718913
Great product, easy to install and works just the way it is supposed to. 695252
This kit was very easy to install and works as expected. I tow a dinghy about 1x per month and this kit has really made the set up a quick and easy job 659190
Great product! Easy, quick install. Works great! All plug and play, no splicing. 624244
My daughter moved the package indoors while I was on vacation. I did not open the package until 9 months later when I first needed it. Part of the components were missing. The box was damaged in transit. etrailer went above and beyond to insure that I received the parts needed to use the unit. Great customer service. I am a very satisfied customer. etrailer is a pleasure to have as a supplier. They worked with me when they were not bound to do so, which is a great quality to have these days. More companies should treat their customers like this. 596475
You product was easy to install and took less than 1 hour. The best part is no splicing into the factory wiring. I have passed on your product information to my serving RV technician. 589650

Randall - 09/19/2019Great product great people and great service I will keep using etrailer for my RV needs. 566220
Ordered the Hopkins tail light wiring kit for my 2018 F150, it fit OEM wiring perfectly. The order came when scheduled and am very pleased, now just need time to hook up to my RV. 557105
Very happy with etrailer for the purchase of a Blue Ox tow bar with needed hook ups for lights, etc and an Air Force One Brake system for my 2018 F150. Crystal did a great job of comparing options and matching pricing from across the web. She offered free installation. The Installer, Shane was awesome, I wanted all hookups hidden by the front plate on the F150 when not towing, Shane came through and then some. Finally, the manager Robert was excellent on follow-up as we had some air leak once we got home. etrailer stood behind everything and follow was exceptional. Very pleased! 553938
Excellent product. Super easy install on 2018 F150. 548038
