Features to know about

Seamless Towing Adventure: Custom Plug-In Harness

Gone are the days of fiddling with your car’s electrical system when preparing for flat towing. The Hopkins Custom Tail Light Wiring Kit simplifies your setup by plugging directly into your vehicle’s existing wiring behind the tail lights, without any messy splicing or cutting. This means a quick install, preserving your wiring's integrity and ensuring a worry-free towing experience.

Lifetime-Ready Durability: Integrated Diodes and Weatherproof Protection

Protect your vehicle's electrical system with the built-in diodes that prevent any unwanted electrical feedback from affecting your car during towing. The included weatherproof box ensures these diodes stay safe and long-lasting despite environmental challenges. This means your vehicle is safeguarded against any electrical mishaps and ready to tow at any time.

Perfectly Compatible Lights: 4-Way Flat Connector

Connect your RV's tail, brake, and turn signal lights with the 4-way flat connector mounted to the front of your car. This handy feature ensures straightforward connections to your RV, so your signals remain in sync, no matter where your adventures lead. It’s designed to be user-friendly and effective, adding convenience to your travel preparations.

Simplified Driving Adjustments: Optional Brake Light Relay

For those using a supplemental braking system, consider adding the optional brake light relay (sold separately) to your setup. This tiny but powerful piece ensures that your brake signals act as expected, maintaining safety for both turn signals and stop signals. It’s an optional enhancement that makes a big difference in consistent towing safety.

All-In-One Package: Comprehensive Kit for Peace of Mind

Everything you need for a secure towing setup is included. The wiring harness, mounting bracket, and installation hardware come all in one package for an uncomplicated installation process. This ensures you have everything required to get going without needing extra parts, keeping your focus on the road ahead.

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.

by:

The Hopkins wire kit was simple to install at the rear of the Jeep wrangler however as a diode connection to the G-Force from Demco’ s stay and play braking system it missed the mark. The piggyback ground white wire did not accompany the entire diode assembly wiring and I’m not convinced that the technnical explanation I received will allow the system integration to work as described with the grounding that was recommended.

Hey, Lawrence. Wanted to check in and see how things were going so far with you. Have you been able to test out the system yet? Was the ground working out like it should? Let me know when you have a chance. If you need more help, let me know.

This product works great!! Easy to install and this is the third vehicle that I have installed the Hopkins wiring in my tow vehicle. I would definitely suggest purchasing this product.

Plug and play. Works great on my 2025 Jeep Gladiator Runixon. Not difficult but a little time consuming.

This plug and play wiring system for a towed vehicle is great and user friendly to install. Very satisfied with this project!

Awesome product. It is so nice to just plug and play. Especially when dealing with the lower voltage needs of LED’s. Thanks Etrailer for providing a this product.

After a year the product still gives no reason for complaints. The simplicity of plug and play, beats having a set of magnetic of lights on your toad. Factory lights work flawlessly and nothing to have to store when not towing.

It's in and working good but the harness is made in Mexico and low quality probably won't last for long



by:

Plugged right up to my 2023 Gladiator and worked when I briefly tested it. The only critique is the packaging doesn't say anything about the harness fitting the JK. Only the JL. Hopkins needs to update their packaging.

Just what I needed delivered quickly.

Alexis a reliably professional guy who I can just email or leave a voice mail and he does the rest. He looks up my vehicle on file and parts history, what the new application is, and what, if anything, I need. He gets back to me with shipping options and all I do is select one and I’m done. The fact that I can email and call him DIRECTLY (I’ve been doing this for 2 years now) manes etrailer stand out as my preference (Try THAT with Amazon).

  • Will Hopkins Flat Tow Wiring Work with LED Lights and Sensors on a 2024 Jeep Wrangler JLU
    Hey Steve, thanks for reaching out again! Hopkins doesn't have any exceptions for their Wiring Kit # HM39VR which normally means it's compatible, but even though this is easier to install than a lot of the other options, from my experience I try to shy away from most of the Hopkins wiring solutions because they just simply aren't super reliable. The best option for your 2024 Jeep Wrangler Unlimited is the Roadmaster Smart Diode 7-Wire to 6-Wire Wiring Kit # RM63MR and is ultimately what...

  • Flat Tow Setup for 2021 Jeep Wrangler Unlimited Sahara
    Hey Ed! It looks like you put together a great list of parts. I'm going to list everything out here with links so it is all in one place, including my suggestions. For a complete setup you will need the following: -etrailer Invisible Base Plate Kit # e98948 (I'm assuming you have the factory plastic bumper) -etrailer SD Non-Binding Tow Bar # e34ZR (includes safety cables) -Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles # RM-15267 (If you do not have ParkSense) -Roadmaster...

  • Recommended Wiring Harness for a 2021 Jeep Wrangler Unlimited W/ Park Assist
    Michael, since your Jeep has the park assist then you are going to need the Roadmaster Wiring Kit with Smart Diodes for Variable Voltage LED Tail Lights # RM47ZR. This kit is going to ensure that your LED lights function as they should while being towed, will prevent electrical feedback, and includes two smart diodes, a wiring harness, a split loom, ring terminals and zip ties,

  • What is Best Plug and Play Flat Tow Lighting Kit for 2022 Jeep Wrangler Unlimited
    Hey Gene, the winner in my opinion is the Curt tow bar wiring kit part # C96JR for your 2022 Jeep Wrangler Unlimited. It has the simplest design without a converter box so there's one less thing to potentially fail. The Hopkins part # HM39VR would be my second pick because it is priced the best and the Blue Ox # BLU79FR would be last because it uses same components as the Hopkins while costing the most. I don't generally love any of the converter boxes or electronics that Hopkins offers...

  • Recommended Custom Tow Bar Wiring Kit for a 2021 Jeep Wrangler Unlimited
    Hey Patrick, so I took a peek and what we have for you and I was able to find the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM39VR which is a custom fitting harness that plugs into your existing wiring without splicing. As far as the Roadmaster Stop Light Switch Kit # RM-751490 goes, you are going to need that with your Roadmaster Even Brake Portable Flat Tow Brake System # RM-9400 to complete install. You're also going to need the 12 Volt Outlet Kit, 20 amps # RM-9332.

  • Hopkins vs. Curt Flat Tow Wiring Harness For 2024 Jeep Wrangler
    Hi J, Honestly the Curt Custom Tail Light Wiring Kit for Towed Vehicles # C96JR and Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM39VR for your 2024 Jeep Wrangler are the same thing. They are both plug-in so you don't have to cut any wires, and the only difference really is the manufacturer (who charge different prices and thus the price difference). Since you were satisfied with Hopkins previously, and they are known to be reliable, I'd go with the # HM39VR.

  • How to Upgrade 4-Way to 7-Way Connector on 2021 Jeep Gladiator Flat Tow Wiring
    Hi Damhwi; I'm assuming you have a 7-way on your motorhome and you want to be able to connect to the Hopkins # HM39VR you bought for your 2021 Jeep Gladiator. You can connect the two using the Hopkins Endurance, Flex-Coil Trailer Connector Adapter - 7-Way to 5-Way or 4-Way Flat # HM47075. What kind of motorhome do you have?

  • Can the 2024 Jeep Wrangler Curt Flat Tow Harness Work with Demco Stay-IN-Play Brake Kit
    Hey Terry, thanks for reaching out! Yes, the Demco Stay-IN-Play Duo # DM86VR wiring can be spliced into the Curt Custom Tail Light Wiring Kit # C96JR but you'll need to add a Diode # RM-690 to each circuit to avoid backfeeding. So this will work, but without using the diodes you run the risk of the backfeed happening. An alternative wiring harness that has a module built in to help prevent backfeed is the Hopkins Custom Tail Light Wiring Kit # HM39VR. Does that help at all?

    For your 2021 Jeep Wrangler Unlimited, you can use either the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM39VR you mentioned, rather than the Roadmaster Wiring Kit with Smart Diodes # RM47ZR. If you choose not to use # RM47ZR and you use # BLU79FR you will not need any additional wiring as this is a plugs into your vehicle's harness. If you choose to use # RM47ZR, then you may need the Roadmaster Brake-Lite Relay Kit # RM-88400 if you use this kit with a supplemental braking...
