Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector
Got this for my 2017 Jeep Jk.... comes stock with only 4pin... need this for a small 6x12 trailer... works great ! Since taped into 4 pin only brakes and blinker works, but that's all I need...
I needed something to enable my 4 pin equipped Wrangler to power the ligts/turnsignals when I move the 7 pin equipped 16' car hauler. Now I can have lights/turn signals when I move the empty trailer around after dropping the Jeep off of it, no longer have to try to maneuver the trailer around with a 38' motorhome.

Pollak 7 Pole to 4 Way Connector Adapter
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.

Hopkins 7-Way RV Style Connector with Molded Cable - Trailer End - 8' Long - RV Standard
7 pin connector separated from cable. I was expecting that "Molded Cable" meant that the connector was fused to the cable insulation but instead, the two separated almost immediately after I installed it. It still works fine as the wires are connected securely inside the connector but with the outer covering pulled out like this, I don't think it will last very long.
Çable good but after putting new 7way plug on truck cable wire colors did not match etrailers picture

Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter
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!

Adapter 4-Pole to 5-Pole Trailer Wiring Adapter - Shorter
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.

Pollak 6-Pole, Round Pin, Plastic Trailer Wiring Socket w/ Rubber Boot - Vehicle End
I found what I thought I needed on the website to prepare our car to be flat towed, but wanted to call to verify. After a short phone call, eTrailer saved me about $50 and got me the stuff I actually needed to get the job done! I won’t shop anywhere else!

48" Long 4-Pole Loop with Cover
The items I ordered will allow me to adapt my utility trailer for transporting my sea kayaks. Curt and Hopkins are both quality manufacturers. On a shipping note, the box arrived at the Post Office broken wide open. Your shipping folks need to wrap small, heavy, items in bubble wrap. Then stabilize it with foam peanuts. Just putting it in a box then stuffing the box with craft paper does not cut it. Items were not damaged so I am good to go.
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.

Hopkins Endurance Multi-Tow 7-, 5- and 4-Way Flat Trailer Connector - Vehicle End - Ergonomic Design
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

RoadMaster 6-Wire Trailer Connector - Vehicle End
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

20 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 30" Ground
Wiring worked perfect for my project. I replaced the wiring on my 14 foot utility trailer. If I was to do it again I would buy the next length up. I would have liked to have a little extra wiring if I was to ever need it.
Worked perfectly with the trailer lights.

Hopkins Endurance 7-Way Trailer Connector Socket - Vehicle End - Ergonomic Design
Well I wasn't able to use this as there was no good place to install on my car without it practically dragging. Not a product problem at all. I tried to return and customer service was fast and super helpful... unfortunately return shipping would eat up any refund. So.. I get to keep it. good quality and product. Very happy with it and wish I could use it. Will keep it for sometime in the future when of course I will need it.
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.
