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.

Hopkins Custom Tail Light Wiring Kit for Towed Vehicles - HM56200

Average Customer Rating:  4.8 out of 5 stars   (459 Customer Reviews)

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.


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.


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.

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.


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.


Great video and support on installation,


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!



Still working like the day I bought it! Great product!

Jeep Wrangler

I bought a complete flat tow parts fir a jeep wrangler. I decided I could install myself. Your installation videos made it nearly a piece of cake. From a quote I got from a RV service business, I saved several thousand dollars installing myself. etrailer is the place to for your RV needs!


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.


Looks good we’ll see how the installation goes


Nice kit,everything you need for towed vehicle.


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



Still working as it should be.

@Justin That's great to hear, thanks!

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.

2007 Jeep Wrangler Unlimited

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.

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.

2015 Jeep Wrangler

Excellent plug & play product! Shipping was fast. Follow-up messages with video links for the product were unexpected and helpful!


Was very pleased with the service and got the right product that I needed.


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.

Jeep Wrangler

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.


Easy to install and videos, very helpfu l.


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

2017 Jeep Wrangler

Great product easy install. I found out on passenger side it was easier to drill with hole saw to pass wire trough cover .then made gromit out of rubber chiar/table cap .Sliced up side and noched for wires snapped right in. Product works great I would recommend .


Great service, products and follow up!


Best towbar like it better than demco towbar and lighter too works great had it one year so far so good

    The Blue Ox Tow Bar Wiring Kit # BLU79FR is designed to fit 2020-2023 Jeep Gladiators and would not be a compatible option for your 2008 Jeep Wrangler. We do carry the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56200 which is confirmed to fit your Wrangler, but I'm not really a big fan of plug-in style diode wiring as it can't be fixed if there's ever an issue.

  • Recommended 4 Pole Wiring Harness for a 2010 Jeep Wrangler
    Max, to install a standard trailer towing harness on your 2010 Jeep Wrangler you're just going to need the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # HM42635. This harness installs into your Jeep's factory wiring and will provide a 4-pole at the rear. Also, according to Hopkins, you can use both the # HM42635 trailer wiring harness and their # HM56200 flat towing wiring harness at the same time.

    Yes, the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56200 and Demco SBS Stay-IN-Play DUO Supplemental Braking System # SM99251 would be compatible with your 2008 Jeep Wrangler. That being said, I'm not a big fan of the plug in diode kits like the # HM56200 because they tend to be wear out quicker and have way more issues than a splice-in diode kit. It can definitely seem scary cutting into the wiring but a splice-in kit like the # RM-15267 is the best way to go to prevent...

  • Flat Tow Wiring Kit Recommendation for a 2016 Jeep Wrangler Sport
    Yes, the Blue Ox Tail Light Wiring Kit # BX8869 will work on your 2016 Jeep Wrangler Sport but I recommend going with the Hopkins Custom Tail Light Wiring Kit # HM56200 instead because it tees in with the connectors for your tail lights instead of having to drill holes into your assemblies and risk breaking something (which isn't uncommon). If you tee in the Hopkins kit and then cut off the 4-Way connector it gives you the same wiring as the Blue Ox kit but it's a much easier and cleaner-looking...
