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.
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 behind your car's tail light assemblies. 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.
Because your vehicle has a combined lighting system - wherein the brake signals and the turn signals are carried on a single wire - 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.

Today we're going to be taking a look at the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles. This product fits certain years of the Jeep Wrangler and Wrangler Unlimited. To ensure that this is a fit for your vehicle, you can use the vehicle fit guide located at etrailer.com. This wiring kit allows you to wire your vehicle and get the signal lights required for flat towing without having to splice into your wiring. The unit features integrated diodes to prevent feedback from the RV allowing for safe operation. Ultimately, the unit's going to let you wire your vehicle to accept your RV's tail light, brake light, and turn signal lights for flat towing. It simply provides a 4-way flat plug at the front of the towed vehicle to connect easily to the motor home. The unit is going to plug in quickly and easily.
You don't have to worry about cutting or splicing any wires. The connection points are located behind your vehicle's tail lights. The unit also comes with detailed installation instructions. This is custom fit for your vehicle. These plugs are going to match up perfectly with the ports on your vehicle. They're going to snap lock together for a nice, tight, secure connection. The unit's also designed to prevent electrical feedback, which is going to safeguard the towed vehicle's electrical system.
This is a nice weatherproof box that keeps the builtin diodes protected at all times. This system, once it's installed, it will not interfere with your electrical system on the Jeep when the towed vehicle is not hooked up to the RV. Again, it is custom designed for your vehicle. It's going to include your wiring harness. It's going to come with a mounting bracket. This allows you to mount the 4-way at the front of the vehicle, so it's always easy to access and just accessible.
That's nice that they include that. It also comes with the mounting screws, so you get that bracket installed. Nice, durable, plastic construction. It's also going to come with a terminal grease packet. You can apply that to the connection points. That's going to prevent corrosion to those connection points. It's going to come with a dust cap for the 4-way flat connector as well as some zip ties.
That way you can secure any excess or slack in your wiring up and out of the way, making sure that the harness is safe and protected. The white wire right here is your ground wire. Has a ring terminal pre-attached to it, so you can easily get that grounded to a suitable grounding point with the included grounding screw. Now an extension loop for connecting the towed vehicle to the RV is sold separately. A brake light relay, part number RM-88400 is sold separately. That may be required if using a supplemental braking system. That's going to do it for today's look at the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles.

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.Plug and Play. I already had a hitch and plug hooked up to the rear, and all i needed was to plug this in to the rear and that harness and it works great. 714755
Have used E Trailer a number of times as always there service is Great. I ordered a trailer towing wiring harnesses for my wrangler (plug and play) and the one they recommend was great 708228
Item isn't installed yet but the order and shipping was outstanding. My order arrived via UPS in just a couple of days. Great job. 681950
Wiring was easy to install and has worked well towing over 5K miles. The only change I made was to remove the 4 pin connector and installing a 6 pin connector to match my motor home cable. 683843
Works just like it should. Easy to install.No issues.Thnanks 700457
This wiring kit for towing a jeep is a must. Easy to install, easy to use and towing and using the jeep tail light is perfect! Thanks Rick 679762
Easier than expected. Took about 20 minutes to install. This was the second time I bought this, installed on my other jeep. 723023
I'm really impressed with this wiring kit. Using the video and the well written directions, the hardest part of this job was running the wire. All the plugs appear to be factory plugs. 705826
A lot easier and simpler than buying diodes and splicing into the electrical system. And etrailer's price sure beats [onlne retailer's] price! I have not installed it yet, but I trust Hopkins quality. 694925
The wiring harness was as easy to install as the instructions described. A couple of hours is all it took. No issues and operates as designed without any flaw. 726935
Product was excellent, and went together in tail lights. However, on Drivers Side, had an bottom insert to pull out, for wiring to tail lights, and on Passenger side had to drill 1 1/4 hole, for wiring to tail light. The other similar product Etrailer carries has a neat video, which I studied. Also, be careful on running the wire across the rear. I had to use 11 inch tie raps on frame, and ran it in very rear frame away from muffler, pipes and moving shocks, torrosion bar, springs, etc. Also, had to work at running wires from back to front. Plan to spend some time on this, and again, get longer tie raps. To tie around square supports I used 1 and 1/2 11 inch raps combining to 11" inch together to make about a 16 inch rap. Hope this helps but I am sure many of you have good ole American know how! One last thing. I think the other similar product, which was not immediately available , has another connection for a rear trailer hitch ? I think I had this was on my older jeep? Would strongly look at this and consider it. E Trailer has this but it had a long back order, so needed something. 127276
I ordered base plate, tow bar and all the goodies to hook up to our RV. Very good service and everything was delivered in 3 days. In the process of installing now. I have ordered parts from etrailer before and they have always been very good. 574633
This product was easy to install and has given me no problems. We have towed the Jeep throughout the year and this product continues to work every time. 674189
Installed this product on a Jeep Wrangler Unlimited Rubicon. I watched the video on installing this product and it really helped with the install. The install was really easy and I like the fact that I did not have to splice into the Jeep's wiring. Highly recommend this product. 168502
Simple installation and excellent quality product! I installed this harness on my 2018 Jeep Wrangler. After one year it is still performing flawlessly. Don’t do like I did on my first tow vehicle and pay someone hundreds to thousands of dollars to do something so easy. Thank you etrailer and Hopkins for easy to follow instructions and videos! 728488
I have a 2016 Jeep Wrangler Sport Unlimited 4 door, after I installed the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles - HM56200, I found I had to install the Road-Master Brake Lite Relay for Towed Vehicles - RM-88400 , I'm using a supplemental brake system, when the brake is depressed with ignition off, the brake lights come on and cancel out any directional signal on my toad, installing the relay solved this problem. I watched the video and this was helpful. Installation took me a few hours, climbing under the dash was not an easy chore for me, I'm not as young as I want to be, had to purchase 16 gauge Red wire to run to Fuse box under the hood, also I recommend having extra wire ties to do this. I recommend both products, easy to install and good quality. 319139
Great product. Watched the video a couple times to get a good idea of what needed to be done. Played video on my phone while installing. Took me a couple hours but was taking my time. Got this and the brake light relay switch that was recommended. Hooked everything up and it all worked great. The videos help out tremendously! Thank you! 195130
Attached very easily, enough wire so nothing was short. The instructions both on video and paper were easy to understand. Anyone can install this to their towed vehicle. 569497
This was very easy to install on my Wrangler Unlimited and ties in very well with the existing lights. I do recommend purchasing the RoadMaster Relay kit. 554254
Product arrived on time and as described. The kit went in fast, and I ran better than 90% inside the vehicle frame. If you're going to purchase this and install on a Wrangler, get a small tube of caulk to refill the hole you'll need to poke in the insulating foam by the tail light assembly. 210885

Perfect fit. All lighting works. Easy to install. 694273
I have purchased from etrailer before. Always received good products in a reasonable time period. This order worked just like the past orders. No complaints. 692176
This was great, I used it to wire a Jeep JKU to my Motorhome for towing. Took my time, and added a split wire wrap to the whole thing, rather than the loose wires as it comes in the kit. Highly recommend this upgrade to make it easier to pass through the chassis and to protect the wiring. Work’s flawlessly! 673801

HM56200 Review: I have a 2017 Jeep Wrangler and needed a way to use the Jeep Tail/Stop/Signal lights. The etrailer staff was very helpful in helping me purchase the correct system. I had a local RV shop install it. No muss, no fuss. Works every time I hitch the Jeep up to my 1991 Hawkins Diesel Pusher Motorhome. I also use the RM-521448-5 Base Plate, RM-676 Nighthawk Tow Bar and the SM99243 SMI Air Force One Brake system for Air Brakes. 5 Stars! 635927
it was a great product and it works GREAT !!!!!!!!!! 633851
Products are perfect and delivery time was amazing! 629568
Very easy installation with the enclosed instructions and viewing several videos on the installation. Very Pleased! 619329
We were disappointed with the wiring kit. When towing the vehicle, if you put on a signal light it works fine until you apply the brake in the towed vehicle. The signal light stops working in the towed vehicle. Once you release the brakes, the signal light resumes working. If we knew this, we would not have bought it. 615608
Parts came in a timely manner. Part was exactly as advertised. Quick and easy installation. 613571
Worked very well. 608439

Great Video Instructons, Perfect Fit, Easy Peasy 601382
Worked great. I have towed my jeep over 5000 miles the past 12 months and this harness did exactly what it was supposed to do. Easy install, but watch the videos to better understand the wire routing. 599644
Good product and very easy to install.fit perfectly as directed 595821
