Most Popular Single-Function Adapter for 2021 Jeep Wrangler

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.

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.

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!

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.

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

I have ordered several adapters and complete trailer wiring harnesses from Etrailer. All have been top quality. I have saved a lot of money on the plug and play trailer harnesses. Several hundred dollars when they are factory installed, less than $75 from Etrailer.

Love the test option on this

It fits, it works. Great choice

product is exactly what was ordered, quick service and a very reasonable price. Adapter plug is just what I needed and is well made.

Arrived fast just like I was told, and great product, simple install

The adapter works great! I used it the day that I got it. I have an 18' car trailer that I just needed to take down to get a VIN inspection and I wanted to use my Jeep Wrangler because it's so easy to maneuver the trailer. I plugged the 7 blade from the trailer into the adapter, plugged the 4 wire flat into the Jeep, connected the ground wire, and the lights and turn signals all worked fine!!!!

It took awhile to receive my order, but I was informed by e-mail and was kept informed when I should expect delivery. Luckily, was in no rush, so I would reply and wait for an update from you. i received the connector in good condition. Thank you!

I have to say this is one quality product. I haven't used it yet however it is exactly what i need for my 8x30' camper which will be my permanent home on some land i own in a warmer climate. this is heavy duty wiring and plugs. fits the bill for me, i am so very happy i found this it will make my life easier, i thought i was going to have to rewire my trailer till I found this set. Very happy with my purchase and prompt delivery. Highly recommend this product and this company, thank you so much for sending it so quickly.

Perfect fit for my Tiffin motorhome, will use the flat plug for tow dolly lights.

Exactly what I ordered. Tried ordering it from Northern tools did not stock it. At etrailer no problem shipped out right away,
