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.

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
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
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
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
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
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
Easier than expected. Took about 20 minutes to install. This was the second time I bought this, installed on my other jeep. 723023
Works just like it should. Easy to install.No issues.Thnanks 700457
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
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
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
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
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
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
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
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
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
Bill K - 07/09/2016This 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
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
