Adapter 4-Pole to 7-Pole and 4-Pole
I installed a trailer brake kit on my Ford Ranger over a year ago, finding the misc parts and install kit with the help of the etrailer Folks. My truck was rear ended recently, smashing the 7 pin connector, that came as one part number for multiple parts, mounted through the bumper. Calling the etrailer folks, they were able to single out the part I needed without buying the entire install kit again. One five minute phone call and I'm on my way again! Very pleased!
I just had to clip a few wires and it plugged into the 4 prong connector on the van and it works as it should

Adapter 4 Pole to 7 Pole and 4 Pole w/Test Lamps
Couldn't get things working on my Jeep XJ. Ordered this set up and everything worked.
Perfect . My new Subaru hitch has a flat plate to which the dealership attaché the 4-flat. I used “2 L-brackets” to accommodate the 90 degree bend of the adapter bracket.

Hopkins 7-Way RV Style Connector with Molded Cable - Trailer End - 8' Long - RV Standard
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.

Adapter 4 Pole to 6 Pole and 4 Pole Trailer Wiring Adapter
This adapter really cleaned up the installation and connected directly to the wiring harness. Maybe added an additional 20 mins to install this adapter but totally worth the time and money.
II use it on my towed vehicle behind the motor home. It allows me to take motor home power to a trickle charger in the towed vehicle and connect to the towed vehicle wiring. The four prong receptacle provides outlet to be used if there is ever in need for a four prong fitting good.

Pollak Heavy-Duty, 4-Pole, Round Pin Trailer Wiring Socket - Metal - Vehicle End
Heavy built. Very much wish it had a cable clamp on the backside similar to its male equivalent. As it is all the strain on the wiring/cable is supported by the terminals themselves.
I've got that trailer that has had one tough life. Yep, hundreds of gigs, PA and sound equipment rolling in and out, the heat, the cold, the sun, rain, and snow. Chicks, guitar players and drummers, you know, all the things that beat the hell out of a drum! Thank the music Gods for etrailer.com! The place to remedy the ills that trailers need in times of harsh environments, tough crowds, tin-ear'd musicians, and you ain't nothing but Hound Dogs!

Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector - Trailer End
It served its purpose to convert 4 connection to 7 connection to make it compatible with Toyota 7 connection set up diagram which is different than many American or other 7 point connection. Thank you E-Trailer . 5 stars and it's working just fine 1 year out from installing.
Used to make a test lead when trouble shooting new GM trailer brake controller and kept as spare.

35 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 42" Ground
Worked out well.
2 things. 1st@: I think there should be an option to pick tinned wire. 2nd: The ring terminal for the ground needs to be bigger.

RoadMaster 6-Wire Trailer Connector - Vehicle End
Note to self: Always push brake pedal firmly before releasing parking brake. especially when Jeep is slightly uphill from Blue Ox tow bar. :-) This was a very quick fix, (unfortunately not quick enough, the wife saw me before I could hide it) maybe took 10 minutes total. A socket set and a small phillips screwdriver are all I needed for this replacement.

Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter
This is for a 2014 Jeep Cherokee Latitude. It took me a little extra time as my helper was a 5 ton floor jack and it supported the receiver and if only my right foot had fingers it would have helped a lot. Loading the bolts and plates into the frame was a snap, I left the fish wires on the bolts and that helped a lot and I didn't lose a bolt into the frame,you must leave the exhaust hanging to get to the rear bolt closest to the exhaust curve just before the mufflers I didn't and it was a bear to torque it. Also after I cut the opening on the bottom of the bumper and already had torqued the receiver I had to pry the bottom edge over the receiver there was no other way to get the hitch up inside not enough forward space to get it to slide up and in. Other than that it was a snap. Now for the wiring harness, went well had a bit of a time getting the connectors up to the tail lights even with all 4 screws out and a little bit of play I had to pry the plastic support away from the body to get the connectors through. That was for the 4 flat, for the power for the harness I have a rig runner 4005 from Powerwerx for all my power as I am a volunteer Fire Fighter and have all the goodies that goes with it and every thing runs fine. For the 5 flat all I had to do was find and take out the backup bulb in the tail light and test to find which wire was hot. And then it was over and done put it all back together and drive away with my trailer. Sorry no picture it looks just like the factory/dealer put it on. Ray H
My trailer has a reverse lockout that requires the back-up light signal to disable its brakes when backing up. This adapter did the trick perfectly.

Adapter 7 Pole to 4 Pole with Tester and Cover
Works as stated, just plug in to7 pin connection on car, and plug 4 pin to trailer. Nice feature w/ led lights to check if connection is good
Would be a good product if it were compatible with my Rivian R1T. The truck detects the draw of the indicator lights and insists on staying in trailer mode. I had to buy one without lights. I may or may not have used the compatibility feature of your website but you should be sure that it is set to not recommend this product to Rivian owners

The person who helped me find the correct part went above and beyond just taking my order and helping me find the correct part. Now I know why my dad suggested that I try etrailer to find the part I needed.
Perfect replacement

Mighty Cord Trailer Connector Adapter - 4-Way Flat to 7-Way RV Style - 12" Long
I added it to my trailer, so when in camp I could have the running lights on without the truck.
You guys are great, professional, keep it up

Trailer End Connector - 4-Flat - Coiled
I used this product along with your 7 round pin to 4 flat adapter, item #118709, on the lights on our Brent and Parker grain wagons. This has worked out great so far. We haven't had the problem of too much or too little cord for the trailer lights, which allows the cord to get pinched and cut or stretched and broke. I just need to come up with a method of securing the cord and plug to the trailer tongue when not in use.
Pretty heavy cord. Feels like good quality.

48" Long 4-Pole Loop with Cover
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

Hopkins Endurance Multi-Tow 7-, 5- and 4-Way Flat Trailer Connector - Vehicle End - Ergonomic Design
Love the compact size for both 7way and 5/4 way connections. Install was pretty easy. The wire instructions are for a traditional 7 way color code. Would be nice if they included a RV color code and heavy duty. But just a multi meter or cross reference with your wires manual is all that's needed. I did not give 5 stars because I did not like the 2 flimsy hook connection to attach the wire shield backing to the connector. I reinforced with some black tape because it was sperated. Also would have liked if the 5/4 way door was spring loaded just like the 7 way. I mounted my connection sideways to use gravity to help keep that flap close.
Heavy duty constructed is definitely a plus there are a couple shortcomings that I was surprised to see.. first off for it to be truly waterproof where the cable enters the back of the plug needs to be more waterproof. Also stainless steel screws were not used and I just don't understand why they are selling a product that cannot stand up to the test of time and these are two rather inexpensive improvements that can be made.

20 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 30" Ground
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.
What our customers are saying:
"Ordered the part on Saturday and had it by Wednesday. $35-$75 cheaper than I could find anywhere else. I plan on using this site again."
