Best 2021 Jeep Wrangler Trailer Wirings

2018 wrangler unlimited Sport S. Without trailer wiring. Completed installation today. Used a 4 flat along with a 7 pin converter. Works and fit perfectly. Very hot day and work slowly and carefully. Very satisfied . Great folks at etrailer. Great products, great quality and prices. I'm a several time repeat customer and couldn't be more satisfied. 4 pin harness Was a 56407 and the 7 pin adapter was a 37185.

Lacking instructions

etrailer rocks! Period. Great Web site, awesome helpful information and videos...and great service.....highly recommend them!

Product is top quality and arrived very quickly in excellent condition. 5 stars !

I purchased the 7-way cord and the adapter to extend the connection from the bumper to my extended hitch connection. The ready made molded cord made it easy to assemble the extension cord. Works as advertised.

Much easier to plug and unplug than the little four flat tight thing.

The plug is different from original cord. Doesn’t look as good but we’ll see how it works. 1st new cord

It's a bundle of wires with a plug. Hard to make this type of part special above other brands. Price is the big factor. Not quite sure why this one is 50% less cost than some others. But works as expected. Solved the dreaded taillights blinking while traveling on the road.

I always look forward to working with etrailer. They sell quality products and provide “old school” customer service...Thanks!

Works, exact fit, high quality, coils tight so max of about 3.5’ perfect! Heavy duty wiring, great waterproof connections.

Heavy duty spring lock will keep the cord where it belongs. Easy install.

Great service, shipment made timely

Can be a little tricky to get the wires clamped in the back of the plug but once installed on the wire, works as it should, and good quality

The install was extremely easy on my 2017 Jeep Wrangler. Just route the wire from the left backup light down to the trailer connector following the current wire bundle. I haven't tried it with the trailer but with the back up lights on there was voltage to the trailer connector, so it should work. Super fast shipping also.

Looked every place for this part. As usual etrailer had it in stock and it came in 2 days. Only place to look for anything trailer related. Great service!

Always a good product at Etrailer.com and informative write up and videos

Just what I needed. ETRAILER Rocks !!!!!

This adapter is wonderful! It continues to work like a charm, was easy to install, and the price was right. Needed it for hauling my boat trailer that has hydraulic brakes. It has made it through all kinds of Wisconsin and Minnesota weather on my Jeep Wrangler and will last like any other wiring part that is exposed to the elements. I highly recommend this to anyone looking to adapt 4 pole to 5 pole trailer wiring.

Great product! I have a Jeep Wrangler Unlimited that only has a four pole flat connector. I have a boat thats needs a five pole because it has surge brakes. This was the perfect solution. I just had the fifth wire connected to the back up light and plugged this five to four pole adapter that was already on the vehicle. Problem solved. It came quickly. I accidently ordered two and I got a call from Etrailer questioning my order. I thanked them and said I only needed one. They saved me the cost of the second adapter when most companys would have just sent them both- and charged me for two.

Easy to wire up and I prefer a metal case versus’ any plastic type. I also have the metal receptacle on my Jeep Wrangler.

Great service, shipment made timely

I have now installed the following on my 2017 Wrangler: Brake light relay kit . Hopkins Towed vehicle Tail Light wiring kit. Blue Ox base plate. Blue Ox Patriot Portable RF Braking System. All of this has taken about 3 days of work spread out over a week or so. Overall it went well. Not too many surprises. Crawling around under a car at 71 is a bit of a strain but I'll get over it. I must say that Donna P. has been a wonderful source of great information and has stayed right on top of the process. eTrailer has been a great source for this project. I would recommend you all with no hesitation.

Works for me??. Just needed a longer one for my utility trailer since I switched vehicles. Always easy and fast to work with etrailer. Thanks again

Installed: 9/12/2013 Jeep Wrangler Unlimited Installation of the plug was a quick and easy. The existing Warrior hitch has a tab on the side for a trailer wiring socket. Drill a new hole on the installation bracket (comes with the trailer connector) so the bracket on the hitch matches bracket on the trailer connector. Done deal. This is the only trailer connector I found which has the 7, 5 and 4 connector options. Flexibility is always a good idea when you are borrowing someone else trailer or renting.

the perfect plug for mt Wrangler tj

Great product and thanks to etrailer.com for the excellent videos detailing how to install the Demco Stay-In-Play Duo braking system. As a result of watching all of the available videos, I learned that there where a couple of different ways to install the system in our Jeep Wranglers. The first installation I did was in our 2019 Wrangler and that was super easy following the one video on your website. The second installation of the system was not as easy because our 2021 Wrangler has a manual transmission and required having to drill a hole in the firewall/floor board to run the wiring and vacuum tube from the passenger compartment to the engine area. If etrailer.com ever has an installation on a Jeep Wrangler with a manual transmission to perform, hopefully they will video tape that installation to guide customers with Jeeps with manual transmissions. I think etrailer.com's idea of mounting the control box on the fuse box is by far the cleanest and easiest way to install the Demco braking system. I also followed etrailer.com's videos for installing the brake light system and the base plate on both our Wranglers and could not be happier with them. Thanks etrailer for all you offer.

Worked great on my 2019 wrangler JL , very easy to install

Quick ship, exactly as described. I buy from etrailer all the time

Good prices,free shipping($99.00+)good products as listed, what more can you want!

Quickly shipped and great value. Very easy to mount and saves time by having two plugs available and not having to switch when using round plug. Great seller and very good product.

Product shipped quickly and was exactly as described. It mounted to my Wrangler in just a few minutes of work.

Just what I needed for my home-built bike carrier. My wife rides an e-tricycle and by the time I loaded the trike and a couple of bikes on this platform, you could not see the car's taillights or blinkers. This harness worked perfectly!

Used this to rewire a 6 x 10 trailer. Inserted the wire through 3 feet of metal conduit to keep it from being damaged near the coupling. So now the only exposed wire is the ¼ inch right at the connector.

I do not recommend this product. I bought this for my truck. It seems to be the nicest looking plug on the market but after the first rain, the plug was filled with water. I changed the location from the hitch to the bumper and once again the plug was filled with water after it rained. This condition will obviously lead to terminals corroding and/or wires being shorted out. I have bought a different style plug, unfortunately the same brand but hopefully I will have better luck. May be able to drill a small drain hole in the casing to allow water to escape but shouldn't have to do this on a new product.

I bought this socket for my 2006 Volvo Xc90 to wire in the 4-Pole harness I also purchased from etrailer. Already had a few 7 Blade to 4-Pole adapters from my previous vehicle, and wanted the option of adding a trailer brake wire for a small camper later on so that was the main reason for the purchase. It also went very well with the Hidden Hitch I had already installed, bracket mounted right up to the existing tabs on the hitch. Super quick and easy install, as all of my etrailer purchases have been. Looks great on the truck, and functions great with the 180 Degree cover.

Wiring harness and flat tow bracket to be able to tow our new Wrangler behind our motorhome. Product arrived on time and everyone was most pleasent to deal with. had the bracket installed by the dealre we bought the Wrangler from as part of that deal and then did the wiring ourselves. Pretty weasy thanks to the excellent video provided by etrailer and it took us rookies about 3 hours to complete. we are very happy with the service and product. Thanks to all. Regards,

Product arrived on time and as described. I used this for setting up our 2014 Wrangler Unlimited Sahara for a flat tow. Mounting hole spacing @ 2" o/c didn't match our Blue Ox 1126 draw bar so I fabricated my own intermediate bracket, polished it to aircraft tooling standards, then lacquered it before final assembly. I think the finished product came out nice.
