- Connects quickly and easily - no cutting or splicing

Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side tail light. You will have to remove the tail light assembly to access this harness.
Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

Great product!
Upon arrival i installed this kit in only a few minutes and was on my way from Pennsylvania to Florida to pick up my boat and tow it back. This wiring kit functions flawlessly just like it was an original piece of my Jeep. If your looking for the right part to add trailer wiring to your Jeep JK buy this kit and you wont be disappointed!
by: James02/07/2020
Knocking one star because it was a pain to get into the etrailer mount that I bought with this harness. See picture. Not sure if it was the mount or the harness being thicker. Wound up chewing the crap out of it as I pushed and struggled to get it through the hole. Not happy with it being all chewed up.
The connection to the Jeep tail light (driver side) was super easy and best install in that regard I’ve ever done.
by: Brian08/07/2023
This has worked great with our towed vehicle. Combining this wiring harness with our choice of tow bar has worked out great. We have put approximately 16,000 miles on our rig without any issues. Thank you!

Very simple plug connection. Just disconnect jeeps left tail light plug. Install this plug between factory plugs. Done. Routed wires along framerail in order to hide as best as possible.

Plug and play, how could it get any easier? Installed behind tail light in less than 10 minutes. Took another 15 to figure out a mount to make it secure. Hopkins made my life much easier with plug and play.

Works every time I plug in my trailer. I keep th pigtail hidden inside my trunk so it stays clean and dry.
by: Bob M06/22/2023
Excellent quality, easy to install. I’ve used it repeatedly in the year since purchase. Highly recommend.
by: Chris05/05/2021
Worked perfectly as a 4 pin. I have been chasing a possible ground (loop?)issue when used as part of a 7 pin, and think that this could potentially (ha!) be related to the lack of a local ground at this location. This has nothing to do with the product... more with the vehicle wiring design. I've provided a local ground to the frame and will take the camper out next week to see if it repeats.

This company have been nothing but understanding and professional. I ordered my parts for my new RV and they came through without a hitch. I liked that I could track the package along the way. Keep up the good work y’all

The Hopkins wiring harness I purchased along with my hitch could not have been any easier to install. I’m totally satisfied with it and would recommend this item to anyone who,like me doesn’t like to be splicing into factory wiring on my vehicles. In my opinion cutting into wiring should be avoided whenever another option is available.
by: Mark C05/07/2020
Excellent! Easy to install and works perfectly. Hundreds of dollars saved instead of getting a new factory wire harness installed.
by: Ralph 05/19/2021
This wiring harness is the best and easiest I've ever bought for a vehicle anybody can install this and it works first time
by: Mark10/23/2020
I ordered these items and I no time at all they arrived at my front door! I was able to track the items, time, place, arrival and departures. As far as the quality of the equipment, extremely well made and top notch functionality. Some of the parts were heavy, but well packaged for safety. I highly recommend this company.
by: Vincent01/11/2018
Went very well only took me about 25 minutes to install the hitch and the lights. I did not need to remove the bumper and in order to install

I tried a set of your submersible LEDs they were ruined in less than a year. I bought the other ones put them up out of the water level they were great.
by: Scott B.10/16/2016
This was a plug and play. Very good quality. The wiring has heat tape around the wires to prevent cutting and heat from the exhaust. With only a screw driver it was installed in about 5 minutes. No splicing.

This product was fabulous. It could not have been easier. I can't believe that it was this easy to get my jeep wired to pull my trailer with lights.

Definitely happy that I was able to buy a plug in harness. Search lots of local stores but couldn't find any then Google showed me a link for the site. Shipping was quick, and pleased with the results.

Great wire harness. I’m an aircraft technician, I don’t get this kind of ease and quality in aviation lol. A person (man or woman) has plenty of time to drink a beer and still install the wire harness in under 30 minutes.

See what our Experts say about this Hopkins Custom Fit Vehicle Wiring
- Recommended Trailer Wiring Harness for 2015 Honda Pilot EXLI do have a solution for you, however as you mentioned in your question, the Hopkins Plug-In Simple Vehicle Wiring Harness # HM42635 is designed to fit certain model year Jeep Wranglers. For your 2015 Honda Pilot EXL, I instead recommend the Tekonsha T-One Vehicle Wiring Harness # 118558. This custom harness will plug directly into factory ports behind the trim panel in the cargo area and under the vehicle on the driver side. This will provide you with a 4-Way connector that will connect...
view full answer... - Will Prodigy P3 Brake Controller Fit 2009 Jeep Wrangler JK Without Towing PackageYes, the Tekonsha Prodigy P3 Trailer Brake Controller # 90195 will absolutely fit your 2009 Jeep Wranlger JK without a factory connector (towing package). To install it you will need to start with a 4-way, if you do not already have one, the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # HM42635. You will then need the Universal Installation Kit for Trailer Brake Controller # ETBC7, which will give you a 7-way connector, circuit breakers and the rest...
view full answer... - Will Hopkins Towed Vehicle Wiring Work With Hopkins 4-Flat on Jeep WranglerYep, your Jeep Wrangler can absolutely use both the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # HM42635 and Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56200. The two will plug in-line with each other so you'd install the # HM42635 first followed by the # HM56200.
view full answer... - Will Hopkins Plug-In Trailer Wiring Harness Fit a 2019 Jeep WranglerThe Hopkins Plug-In Simple Vehicle Wiring Harness # HM42635 that you referenced is a fit for 2007 - 2014 Jeep Wranglers so for your 2019 Wrangler you will want the Tekonsha T-One # 118786 instead. Hopkins currently doesn't have a wiring option for you (as of May 2019) and we have found the Tekonsha wiring to be the most reliable on the market. The T-One has the same type of plug-in connectors as the Hopkins that you referenced but it also has a hot lead that you route up to your battery...
view full answer... - Trailer Lights Wiring Harness 2014 Jeep Wrangler Unlimited with 5 PolesMy advise is based on the assumption that your trailer with a 5-wire connector is a boat trailer and the extra wire is blue and locks out the trailer brakes when you are in reverse. The easiest way to determine if your 2014 Jeep Wrangler Unlimited has factory tow set up is to have the dealership run the VIN for you and let you know how it was equipped. The tow package would have at least included the tow hitch and tow wiring. It seems unlikely that someone took the hitch off of your...

Both provide you with the tail, turn, and brake light. The Curt harness has a 1-year warranty while the Hopkins wiring harness has a 90-day warranty. The harnesses plug into the vehicle wiring located behind the tail lights To install these harnesses you will need to remove the tail light assembly to get to the wiring. When working with electrical...

The Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # HM42635 will plug into your factory harness in your Jeep without factory tow package. The Curt Trailer Connector Adapter - 4-Way to 7-Way RV and 4-Way Flat # C57672 will be able to plug into your newly...

For that you would want the part # HM11142464. We have confirmed this as a fit with Hopkins so we know it will work well. If you have something totally different in mind send me the picture you mentioned.

- Troubleshooting Hopkins Tow Wiring on 2014 Jeep Wrangler Unlimited Cause Motorhome Light MalfunctionThe only 2 things I can think of as to why the Hopkins Custom Tail Light Wiring Kit # HM56200 on your 2014 Jeep Wrangler Unlimited might be causing this to happen is if there is some corrosion and/or debris in between the tees you made behind your tail lights, or if for some reason you need to swap the order in which the tees are connected for this wring kit and the Hopkins Trailer Wiring Kit # HM42635 you also have installed. We've found that 2 of these tee-type wiring kits can be used...
view full answer... - Can 4-Pole Trailer Wiring Harness and Flat Towing Harness Be Used at Same Time on 2012 Jeep WranglerAccording to the folks at Hopkins, you can indeed use the # HM42635 trailer wiring harness and their # HM56200 flat towing wiring harness at the same time. I've linked to the installation video for the flat towing harness and instruction sheets for both parts. I've also linked to an article that runs through all the products needed to safely flat tow your Wrangler.

The towed vehicle does not have to be running for this signal to be active.

The tow vehicle does need to be running for these signals...
view full answer... - Hitch, Wiring and Other Towing Items Needed for 2010 Jeep WranglerWe can help you get your 2010 Wrangler set with a hitch, wiring and other items for towing. The hitches made for your Jeep are intended for models with the standard rear bumper. You can see them all on the linked page, but the one I recommend is the highest-capacity model # DT78MR which is rated for 675-lbs tongue weight and 4500-lbs towing. I linked an installation video to show you how it installs and a helpful article is included too. The hitch comes with the hardware you'll use to...
view full answer... - Adding a 7-Way Trailer Connector and Brake Controller to a 2008 Jeep CommanderWe can get you set up with a 7-Way trailer connector and a brake controller for your 2008 Jeep Commander, no problem. First, you will need to install # 118408 which will provide the light functions to the 7-Way. Once that is installed you can then install # ETBC7. This will add the 7-Way, retain a 4-Way connector as well, and include the necessary components to hardwire in a brake controller. For a controller I recommend the P2 # 90885 because it is easy to set up and use and it is reliable....
view full answer... - Will the Hopkins # HM42635 Fit a 1995 Jeep CherokeeWe do have an option for you to add a 4-Way flat wiring connector to your 1995 Jeep Cherokee, but the Hopkins # HM42635 that you referenced is not confirmed to fit. What you will want to use instead is the Tekonsha # 119178KIT which is a hardwire installation that uses quick-splices to make it easier. Installation instructions have been attached for you to reference. If you will be towing with your Cherokee but do not already have a trailer hitch then I recommend part # 75054 which I...
view full answer... - Recommended Wiring Connector for 5-Way Boat Trailer Connection with 2009 Jeep Wrangler UnlimitedWe do not carry a 5-pole wiring harness that is vehicle specific. For your 2009 Jeep Wrangler Unlimited, you can install the 4-way # HM42635 and then splice in the vehicle side 5-way flat # HM47900 using butt connectors like # DW05744-5 to give you the 5 way. This will give you the connection without the adapter # 47515 needed each time as a 5-way will still work with a 4-way connection without issue and be a better connection for your boat trailer's 5-way. Your other option is to use...
view full answer... - Parts Needed to Install Curt Echo on 2010 and 2019 Jeep WranglerYou'd first need to start with a 4-way on both vehicles. For the 2010 Jeep Wrangler you would want the part # HM42635 and then for the 2019 # 118786. Then to convert to a 7-way for both vehicles you would need the # ETBC7L which was designed to activate the circuits needed for the Curt Echo part # C51180 to work and you'd be set.

For your 1987 Wrangler, I recommend the Tekonsha 4-Pole Hardwire Kit with Circuit Tester # 18252. This will be an easy install with the circuit tester and quick splice connectors to give you a working 4-way trailer connection. Your 1987 Jeep Wrangler did not have the factory wiring connection points to utilize, but...

It's for model years from 2007 to 2014. If your Jeep doesn't include the tow package I recommend the Tekonsha, part # 118416. It plugs in behind the driver's side tail light. If you do have the tow package instead use part # HM42190. See the picture I've attached. If you have this connector under the rear of your Jeep then you have the factory tow package.

It installs on a standard rear bumper and has a Gross Towing Weight (GTW) of 4,500 lbs and a Tongue Weight (TW) of 675 lbs. Be sure to check your owner's manual to make sure you can safely reach those weight capacities. For wiring I recommend the Hopkins part # HM42635...
