Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector
This product works as expected. There is not too much to the installation, just plug it in properly and mount the ground wire. I did not find an easy way to mount this to my wife's Odyssey, or to the trailer hitch (item# 75270). Luckily, I do prototype design and manufacturing. So I came up with my own solution. I designed and made my own bracket to mount the 7 pole to the trailer hitch. It works like a charm, and looks great!
this connector along with the short L bracket and the mount bracket- gave me a nice connector to my hitch. Though I used the short connector and did have to slightly bend it to allow the 4 to 7 pole connector to fit. If Id bought the long L bracket-- It could have worked-- but bending a little worked well.

Pollak 7 Pole to 4 Way Connector Adapter
This adapter plugs in to the OEM receptacle without any excessive effort and the flat 4 pin connector on my utility trailer also plugs into the adapter without any excessive effort. As a bonus there is a cover for the 4 pin side of the adapter to protect it the elements when not in use.
I wanted one with a LED tester built into it to "trick" my SUV into thinking I had a trailer connected when really it was just a bike rack so the car didn't slam in it's brakes while reversing thinking it was something else. So I bought a different adapter. The picture slightly deceived me into thinking this had LED tester because the plug is attached by a rubber string (that I thought was a wire). So add another picture of the other side and that would eliminate my confusion. 4 stars because it probably works the way 99% of people would want to use it for.

Adapter 4-Pole to 7-Pole and 4-Pole
Really nice trailer wiring adapter. Very easy install. Takes about 30 minutes with all the tools needed. Drill, 7/64 bit for pilot holes to mount the bracket, flat blade screwdriver and 11/32 nut driver and two #10 self tapping metal screws with locking split washers and a couple zip ties to tidy up the wiring harness.
I looked at so many options before deciding on the B&W hitch, but I have no regrets buying it. There is nothing that my car is suitable for towing that this thing can’t accommodate. I even use it on the front hitch of my mower to move trailers around the yard! Adjusts very easily and stows nicely (though on my Ford Edge it rides lower than I like when stowed).

Pollak 6-Pole, Round Pin, Plastic Wiring Socket w/ Rubber Boot - Vehicle End
Used on tow vehicle for hooking up wiring harness to motorhome
These connectors were high quality by a known manufacturer. I could have bought them locally but I wouldn't have gotten the expert advice and detailed information that I was able to get from eTrailer!. I talked to several people and each one was very knowledgeable. When the parts arrived, it surprised me because they came so quickly! I would readily order from them again if I needed more trailer parts. I used these connectors to adapt a Minn-Kota trolling motor to my fishing kayak and have attached some pictures showing it installed.

Hopkins 7-Way RV Style Connector with Molded Cable - Trailer End - 8' Long - RV Standard
Used this to replace a failing camper connector. Works fine. Four stars because it's just a cable.
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.

35 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 42" Ground
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.
Replaced the wiring and lights on my 1992 boat trailer. I was able to get everything needed from etrailer. I think Optronics is of the highest quality and recommend both etrailer and Optronics product.

Pollak Heavy-Duty, 4-Pole, Round Pin Trailer Wiring Socket - Metal - Vehicle End
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!
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.

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.
This was my original, but the pins got pushed out the back, so I tried another popular brand, only to find the all-metal assembly put the possibility of the wires shorting out within the "risky" category, so I went back to the non-metallic part, which won't "short" out and cause a problem. Fingers & toes.

Adapter 4 Pole to 7 Pole and 4 Pole w/Test Lamps
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.
I recently had a receiver hitch installed on my 89 Silverado and the wiring was merely zip tied to the safety chain connection. Well that didn't sit well with me. I wanted a more permanent wiring connection point. So I purchased your 4 flat to 4 flat and 7 way plug and installed it. So far so good. The installation turned out perfect and it looks good. The test lights are a great thing as well. I couldn't be happier.

Hopkins Endurance Multi-Tow 7-, 5- and 4-Way Flat Trailer Connector - Vehicle End - Ergonomic Design
This brake hitch connection is worth the money and is a very solid wire connection to my trailer. Works with 3 different connections so I can’t complain at all.
eTrailer has come through again for us. Our 7/4 pin tow connector failed, and they were able to ship the same day we ordered. Our first stop to shop for anything our 5th wheel RV needs is eTrailer.

Pollak 6-Pole, Round Pin, Trailer Wiring Connector - Trailer End
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.
It’s nice to have an inexpensive replacement part rather than buying another whole harness!

RoadMaster 4-Wire Connectors - Trailer and Vehicle Ends
I periodically pull a 12v pressure sprayer behind my lawn tractor. The 12v harness I originally made that clipped to the tractor battery was always cumbersome and became hazardous when it recently shorted out due to rubbing (and no fuse in line). So I finally took the time to do it right, mounted this connector to the rear next to the taillight, and created a hidden fused permanent harness to the battery, and of course utilized the mating connector for the sprayer harness side. This little connector was perfect, high quality materials (connector body and electrical terminals), high spring force on the cover when not in use, nice sealed design yet easy to plug/unplug. Very happy with this purchase and will likely buy it again.
good quality connector just what i was looking for

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.
I love the new setup for my truck. I changed the receiver to a Draw-Tite Ultra Frame model and mounted the connection on the receiver. It works great and accommodates both of my trailers with the 7 pin and 4 pin connections. Couldn't be more pleased. My rewiring of my light trailer is flawless, solid connections and good quality. Thanks!

Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter
Simple and easy to use; just plug it in and connect it to the trailer harness. Works like a charm!
Not installed yet but looks as good as one used before in a former vehicle. The actual adapter I received is "Reese", which is a reputable brand for towing accessories.

Hopkins Endurance 6-Way Trailer Connector Socket - Vehicle End - Ergonomic Design
Worked for me. I used the six wire even though I only hooked up 4 for the toad. The RV 7 blade allowed me to bring a power lead to the toad if I ever need it for charging or power the Aux Brake unit. The bracket could be rotated in any direction and I found the best way was to rotate 90 degrees and install to the base plate. My toad grill made for a tight fit for both break-a-way switch and light connector, but they fit side by side with the addition of an L bracket for the break-a-way. The wiring connections seemed solid and water tight. Wired correct 1st time, No Problems.
The screws that holds the wires are to small. I would have liked them to be more robust. But it did work, but since I just installed it I can’t attest to it’s longevity.

Exactly what I ordered. Tried ordering it from Northern tools did not stock it. At etrailer no problem shipped out right away,
fits the plug perfect....just got a goldwing used, haven't had a chance to ensure it (the bike) was wired correctly for a trailer. no fault of the product, just wish its wireing was a bit long due to the way the plug was intigrated into the underside of the tour trunk.

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!
It's a simple item but try to find it somewhere else as a stand alone product. I've used etrailer before with great results and this was no exception. Let's be honest, if you've been to the site once, you're coming back! I have a 5 x 12 utility trailer that has good lights but the wiring was a disaster. The harness connector had been patched and there were at least 5 splices throughout the lines. It was nice to lay out the new harness, make the light connections, tack everything up and out of harms way (there's an idea) and my lights work like new. I like the ground fastens under the jack bolt. Saves drilling a screw in (see the baby hole?) Good to feel safe on the road again. As easy and inexpensive as it was, I don't know why I waited so long.

RoadMaster 4-Wire Connector - Vehicle End
We just finished a makeover of our 1995 boat trailer. New bunks, sanded and painted but the best part of the project was the new LED lights from your company. They are so much brighter than the old incandescent bulbs that you really do feel safer driving down the road. We pulled the 20 year old wire out and replaced with new and used the 3M scotch loks to tie in. We were not sure the new style grommets would fit the old holes in the frame but they fit great. Your customer service was great, alerting me to a backordered reflector but recommended a replacement that worked fine. Patrick set up a Q&A page for me since I had questions about the best way to protect connections with dielectric grease, heat shrink and tape. Your website is one of the best with ease of navigation, complete pictures, great selection and thorough info, dimensions, etc. You guys really have your act together and also offer great value. I would not hesitate to purchase again and will recommend you when I can. I have attached a couple of pictures. Thanks for all your help. Wayne N.
The Roadmaster 4 wire connector is very good quality to connect my vehicle to motorhome.

Pollak 6-Pole, Round Pin, Trailer Wiring Socket - Exposed Terminals w/ Rubber Boot -Vehicle End
Used this as the connection point for the Roadmaster diode wiring kit. Seems to be well made and will hopefully last a long time. I did spray paint it flat black so it blends into the front bumper of my “toad” a little better.
Very sturdy and secure attachment, much better than the cheaper plastic ones that I have had break before. However, the rubber boot doesn't stay around the wire attachments
What our customers are saying:
"Very broad selection and outstanding service."
