Tow a trailer with either a 7-way or 4-way plug with this dual vehicle-end connector. Included pigtail harness hardwires into your vehicle and the connector end mates with the 7-pole socket to form a weathertight seal.
Quality is good, but wire colors aren’t standard and there were no instructions in the package for how to wire. I had to google standard pin outs and colors. Pigtail is too short, by about 2 feet and I had to splice twice to make it reach the inside of my vehicle (GMC SAVANA). Once I did all that it worked perfectly but what should have been a 1 hour job turned into an all day project. Do not recommend. Go to your nearest RV store.
The service provided by George and Lacey was the best part of this transaction. Lacey helped me find the right parts and sent me a video about installation. They both worked to correct my order and customized the delivery date.
The parts were precisely what I needed to get power to the bumper for a small trailer and bike rack. A few comments: order more butt connectors as the mfr sent 6 and there were seven wires on my Colorado. When connecting the tail harness to the truck harness, be sure all the wires on each side are the same length. The yellow wire strippers take some getting used to, so practice on several wires first. I’m an ‘average’ handy person so these last two suggestions didn’t come naturally to me, but overall this was a pretty simple installation. When I tested it and all the lights worked, I was a happy camper.
Installed the "7-Pole and 4-Pole Trailer Connector Sockets w/ Mounting Bracket and Wiring - Vehicle End". Simple and easy to follow instructions and video.
Mounted perfectly to existing bracket on 2008 F150 Lariat with factory towing package, cut off connector from wiring harness and heat shrunk wires together to existing harness

Perfect!
Easy installation! Kit only supplied 6 connectors when there were 7 wires ...... oops!

Steve, the 6 connectors are correct. The ring connector that attaches to the ground wire is the 7th connector.

I still like the wiring harness I purchased from your company last year. Thank you for asking.
This is a fantastic quality part and an excellent alternative to Ford's OE connector (the difference being this one is far less expensive and does not have the Ford emblem. I used the connector to replace the 7-Pin/4-Pin combination plug on my 2002 Ford Super Duty after swapping the bed/bumper/tailgate from a 2012 Super Duty. It is a vastly superior connector in that the 4-Pin is integrally wired with the 7-Pin as opposed to having the 4-Pin spliced into the harness. I would definitely recommend this part for any towing rig. I eve put one on my father's 1995 Dodge Ram 2500. Don't hesitate to order this one!
I have a 2017 SantaFe I have 2 different trailers and need both types of plugs I am using this product along with a curt class III hitch and a curt 56332 wiring harness.
I want the finished outlet to be behind the factory cover I had to modify the Hopkins bracket by bending it in the opposite direction on a angle because the hitch is in the way .a little effort and its great

The trailer plug went bad on my 92 F150 several years ago. This plug is the same as my 10 F350. I like the combination 7 spade/4 pin. Other combos have a rubber flap to cover the 4 pin plug. I doubt I’m that disciplined and I would think that rubber cover would dry rot and break off. This plug has spring closure doors and looks great!
This item came relatively quickly (with a slight delay due to a backorder, but E-Trailer communicated this very well). The directions, the fit and the on-live install video is very helpful. Please watch the video to be sure you are getting the wires crossed correctly - the wire colors from the harness and the factory wires do not all match so be careful there. Highly recommend this product.
Bought this trailer connector to use instead of the flat 4 wire connector. Wanted a nice finished look on the rear of the vehicle without any hanging wires. Mounts to the Draw Tite mounting bracket without any modification. Only minor problem I had was with the wiring. The wire colors are not the same between the 4 and 7 pole connector. A call to etrailer got the problem resolved. Great customer service!
This is a great affordable option to replace your worn out or damaged OEM trailer recepticle. The fit is perfect. It is made by Pollak which is the same as the Ford one you replace. I damaged mine and took the pin connectors out of new housing and installed it on my F350 without splicing wires. Worked perfectly.
Great product!
Fits the factory hole in the bumper perfectly.
Attaching the wires was a pain but that was due to GM saving $1 by just cutting the wire ends and not installing a plug......but they were all there so that was a plus.
If you do install this setup AND you install a hitch, leave the spare tire down while you attach the wires. There's plenty of wire with the plug but the factory wires are up kinda close to the underside of the bed so not a lotta room.
ALSO spend the extra couple dollars and get the heat shrink butt connectors, they're available here in whatever size you need.
Another thing to think about, if you plan on eventually installing bed/ cargo lights any time soon, now is the time to add that extra power wire before you crimp, shrink, and tape the hot wire......
This is the same look as a factory install. I was greatly pleased with the overall installation. Super easy to wire up and looks great in the bumper. My truck has the clean factory look for way less than what they had quoted for an install.

Installation installation and wire color coding information is provided and linked above in the product description.
This, combined with Item #e45ZR and Item #C68JR, worked great to add both a 4 way and a 7 way harness to my 2021 Kia Telluride. I only used the harness from the Item #C68JR kit, not the socket. I replaced the socket with this item.
The new shoulder connector will fit perfectly. I watched installation videos on you tube and the product I received worked just like the video.
I’m glad I chose this over a single plug! No matter what you have on the hitch, you’ll have the plug for it. The pigtail is plenty long enough and the bracket makes for a simple installation. Get some shrink tube or shrink wrap butt connectors as the ones included aren’t going to keep weather out for long.
Perfect connector for what I was looking for on my 2019 RAV4. I originally installed it with the L bracket, but later changed it to be flush in the bumper. Looks very clean. The prefab pigtail made install into the car very easy as well.
Nice upgrade in place of 4-wire-only. Looks good, works good.
Only gripe, the plug wiring on the back is at a 45° and the plug in on the front is at a 90°, so dont wire up the wires by the wiring plug but how the plug in on the front would plug in, I made the mistake, but other than that, works great, looks great, fixes botched wiring like my truck had with just twisted together and taped up wires, easy install
Bracket is most likely 14 gauge (measured it) and should be easy to weld. Connector appears to be of reasonable quality, but time will tell if it holds up or not. No matter, welding the bracket to my rollpan will be the difficult part, not replacing the connector housing, should it fail. Hard to rate something I haven't used, so first impressions, I guess it's a five star.
Good product instructions easy to follow, the final product looks great.
Good deal perfect fit
easily connected. liked direct wire system. however lights worked at first, now all are out but brake lights. I think this may be due to the connectors used. havent had time to trouble shoot it yet.
When I purchase this wiring and plug kit they said it was for a Chevrolet pickup. I used it on my 1996 Ford f250 only difference is color of wires. easy to figure out. works great and good quality product
Fit like a glove where the plug was in the bumper. Easy to convert the four pin flat to the 7 pin using etrailer parts and instructions.

For Hopkins wiring they follow the following wiring scheme: Red = Left turn and stop White = Ground Blue = Electric brakes Green = Right turn and stop Black = Battery Brown = Running lights Yellow = Reverse lights. If you need to add additional wire we do carry jacketed 7 wire by the foot as part # DW04914-1.
