    • Provides 4-way flat plug at front of towed car to connect to motor home
  • Plugs in quickly and easily - no cutting or splicing of wires

Wiring Your Towed Car with Hopkins

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.


Do You Need a Brake Light Relay?

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.

Relatively easy to install, worst part was routing the wiring to the front of the jeep. The rest was plug and play. I also replaced the flat four way plug with a six pin round.

Still working like a charm! 2,000 miles of carefree towing.

2008 Jeep Wrangler Unlimited

Called my local trailer and flat tow company in my area and they quoted me $179.00 for the harness alone. I also got a quote for the install which was $350.00 and the total of $529.00. Called Etrailer and purchased the Hopkins harness that was on sale and paid total of less than $82.00. It took me around 2 hours to install with wire loom protection. Etrailer has always had excellent customer service. Big thanks to Brandon for all his help.



by:

Haven’t installed this yet but it looks to be great quality and the plug and play installation was very appealing to me. No cutting or splicing of the factory harness and no more magnetic tail lights.



by:
2016 Jeep Wrangler

System works perfectly. Prepare to be patient running the wires between the back lights and to the front of the toad. It is not too difficult, just takes time. I installed it on a 2016 Jeep Wrangler 2-door and have towed it on seven outings covering 2,653 miles with no problems.



by:

I’ve now installed both ‘cut wire’ and the plug and play and the plug and play is by far the easiest way to install. Couldn’t be happier with the ease of install.
Justin was a great help finding what I needed.
Thx again.

I am a 55 yr old woman and I installed this myself with the assistance of the wonderful folks at etrailer. Thank you John G for all the info and making sure I purchased the correct parts for my jeep.

The custom Hopkins wiring harness I installed on my 2008 Jeep JK has performed flawlessly. The harness sure beat trying to figure out the wiring and connections myself.



by:
2010 Jeep Wrangler

The shipping label was printed on 02/01/2024 I received it late on 02/10/2024.
When I purchased it the delivery date said by 02/05/2024.
I'm leaving on a long journey on Monday in my motorhome and towing my Jeep Wrangler, I needed this installed before leaving.

Looks good we’ll see how the installation goes

Easy install. I did swap out the 4 pin head for a round six pin and everything seems to work well.

@Justin That's great to hear, thanks!

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!

Doesn't get much easier than this. Truely was plug and play. Wish it came with a six pin connector option, but a great product.



by:
2015 Jeep Wrangler Unlimited

This harness works great for flat towing a Jeep Wrangler. The installation was straight forward and easy. It's nice to not have to run magnetic lights from the rear of the Wrangler to the tow vehicle anymore. Now, I just plug in to the adapter on the front aftermarket bumper.



by:

My friend who is a mechanic wired it for me. He didn't seem to have any problems. Lights and brakes work great.



by:

The kit was a breeze to install and everything fit just like it stated on the instructions. It's as easy as just plug in and go with my 2017 Jeep Wrangler JKU behind my RV. I would highly recommend this product to anyone especially any Jeep owner. etrailer really did their homework on engineering this product for my type of vehicle which made the installation so simple.

The wiring product was perfect, but the video instructions for my Jeep were even more perfect!

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.

If this does not solve your problem then the converter box isn't correctly sending signals and will need to be replaced. Since you just purchased this...

  • What do I Need to Flat Tow a Jeep Wrangler JK with Factory Bumper
    To flat tow your Jeep Wrangler JK behind your motorhome, you will need a base plate kit, tow bar, safety cables, tail light wiring harness, and a supplemental braking system. Depending on the year of your Wrangler, you may also need a Brake-Lite Relay, # RM-88400, (2012, 2013, 2015-2018) or a Stoplight Switch, # RM-751452 (2007-2011, 2014). For your base plates and tow bar, I recommend using the Roadmaster Direct Connect Base Plate Kit, # RM-521448-5 for 2010-2018 or # 1429-3 for 2007-2009,...

  • Is There A Plug-In Towed Vehicle Tail Light Wiring Kit Available For A 2017 Ram 1500
    No, the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56200 is only for select Jeep Wrangler models. For a 2017 Ram 1500 there isn't currently a plug-in lighting kit so you would need a splice-in kit like the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. Splicing into wiring can be intimidating, but I've attached a short installation video below where Ryan will walk you through the process.

  • Replacing Malfunctioning Flat Towing Wiring Harness on 2014 Jeep Wrangler
    From what you describe, the the relays in the converter are going bad, and my contact at Hopkins agrees. The relays aren't readily accessible and aren't designed to be replaceable, so your best bet would be to replace the # HM56200 harness entirely. Or, you could go in a different direction with a more reliable hardwired system like the # RM-15267 from Roadmaster. Installation of this product would mean tapping into the wiring harnesses for the taillights of your Jeep, but this installation...

    As long as you follow the owner's manual for setting up your 2016 Jeep Wrangler then you won't see a change in the odometer after you flat tow. If you do see a change then you probably didn't set it up right. For a complete flat towing setup you will need a base plate kit, tow bar, safety cables, vehicle tow bar wiring, a supplemental braking system, and possibly a high-low adapter.

For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle. This comes with a round 6-way connector that you will install on the front of your towed vehicle and enough coiled wire to go from there to the RV.

If you need other parts to setup the Jeep to be towed I recommend using the Hopkins wiring kit, part # HM56200, for lighting. It plugs in behind the Jeep's tail lights and provides a 4-way at the front to connect to the RV.
