Adapter 4 Pole to 7 Pole and 4 Pole w/Test Lamps
Not too difficult to install, but I would recommend using a car lift so you don't have to work from your back (review includes wiring harness and Brake Controller)
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.

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!

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.

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.

35 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 42" Ground
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.
Works very well after re-wiring trailer lights with waterproof distribution box.

Pollak Replacement 7-Pole, RV-Style Trailer Connector Socket - Vehicle End
It is a direct OEM replacement, easy installation. What I liked most was a real person answered my call and took my order, Katherine was very polite and knowledgeable. Thanks again. CJ
Worked out awesome. I bought this for a buddy for his used truck. The previous owners for what ever reason took it. Plugged it in and worked flawlessly.

Pollak Heavy-Duty, 4-Pole, Round Pin Trailer Wiring Connector - Metal - Trailer End
Great place for any trailer needs. They alway gave what I want at a good price and fast shipping.
Just what we needed to make a custom harness for our boat trailers that we often tow with light and medium-duty wreckers. No more zip-typing our wireless drag lights to the trailers! Thanks, guys!

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.
Your sales staff is second to none. Keep up the good work. You shipped minutes after I placed my order! Very impressed! Marty

Pollak Trailer Connector Adapter - Vehicle End - 7-Pole Round to 7-Way Blade
I received this item in a plastic bag, for a few moments i wondered if it was a knock-off. I had done my home work and was sure that this item would be compatible with the socket on my John Deere 2013 5085M at the time I ordered it, not so. The 'holding ridge' at the plug-in end was not in the right position when fully inserted into the plug on the tractor. I sent multiple pictures to Pollack Technical Support but they were unable to assist me. I finally modified the item myself (something I really hate to do) so that it would fit the plug-in and be 'grasped' by the cover/holder on the tractor side. As I anticipated, the thickness of the plastic was inadequate to make the adaptation 'sweet', so I had to cover the resulting hole with silicone caulk.
This is a great solution for adapting RV blade connector to 6 pole connector. I give it 5 stars. I use this for work purposes, and have found one issue that I DON'T believe to be manufacturer defect. In my industry we use different trucks and trailers daily, if not hourly. Some trailer electric brakes will lock up when adapter is connected. I have found the red wire in the adapter to be the problem. My solution was to splice in a switch so that when the intermittent problem arises I can flip the switch and be on my way.

Hopkins 7-Way RV Style Connector with Molded Cable - Trailer End - 8' Long - RV Standard
Çable good but after putting new 7way plug on truck cable wire colors did not match etrailers picture
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.

Curt Trailer Connector Adapter - 4-Way to 7-Way RV and 4-Way Flat
I just installed this on my 2015 Volvo XC70. I also used the Curt XC70 plug and Play for wire kit. I watch two of etrailers excellent insulation videos. Installing the hitch and both the wiring products took me around 3.5 hours. I think Curt products are great and they are reasonably priced! e-Trailer makes your DIY installations easy. You just need to take your time when removing interior panels and double check your work. I used Volvo's torque specs for the bumper parts when I installed the hitch. E-trailer doesn't stop with just hitches and wiring solutions, they have just about anything you need to load and haul overhead or behind safely. What about performance? E-trailers got you covered. If you get in a jam during the insulation, don't fret or worry, call the text at e-trailer and they'll walk you through it. I want to thank E trailer and their professional staff for helping me with my truck and auto towing and lighting solution for over 10 years now!
This was/is a critical piece of any towing system, and as such requires extra care to hook up properly . I would recommend testing each connection as you hook it up being extra careful to make sure you are matching the terminals in the mating connector properly. This harness/connector performs perfectly when properly installed.

Hopkins Endurance Multi-Tow 7-, 5- and 4-Way Flat Trailer Connector - Vehicle End - Ergonomic Design
Works great and etrailer folks did an outstanding job with quick turnaround and communication…thank you!
Exactly what we had been looking for. Now I can hook up multiple trailers with different connectors and all the electrics on each trailer works. I mounted mine directly to the receiver hitch frame. The biggest challenge for us was routing the backup wire from the taillight housing, through the body of the truck to the connector. the rest went together fairly easily. Seems to be pretty solid and looks much better than the loose pigtail connector it replaced.

Wesbar 4-Way Flat Trailer Wiring Harness - 20' Long
I'm extremely satisfied with the wesbar 4way flat trailer wiring harness I purchased from etrailers.com. It was very easy to install with no problems. As long as you connect the wires correctly (example) white wire to white wire brown wire to brown wire you won't have any problems. If I ever need another one I'll know who to order it from etrailer.com.
1 year ago, I ordered a wiring harness for my trailer, It worked out perfect. I would recommend "etrailer" to everyone.

Hopkins Multi-Tow Trailer Connector Adapter - 7-Way to 5-Wire Flat/4-Wire Flat and 12-V Power Socket
Good solid unit that I expect to last a lifetime. I purchased this unit primarily to provide a charging port for a float charger. The idea being that if I forget about it or if someone else drives my truck and is unaware that it is connected, it will easily disconnect when the vehicle is driven away.
Perfect! I use the 4 flat for my boat trailer lights and the +12v I've wired to charge the boat battery as I drive to and from where ever I'm fishing; brilliant!

7-Way Molded Trailer Wire Connector, 6' Long
Only gave 4 stars because it was a bit confusing. I have a lot of auto wiring experience; from car stereos,amplifiers and all manner of accessories. All of the info on etrailer indicated that the color coding didn't match up. So I went into it disregarding the standard color coding, when in fact it was just as it should be.
Good thick rubber and plug works perfectly.

Pollak Black Plastic, 7-Pole, RV Blade-Style Trailer Socket - Vehicle End
As the video indicates, ensure that your vehicle wiring is the same as the 7 blade definitions. Mine was not. Had to determine what color wire connections to use for a 4 flat adapter use on a dolly.
Service from erailer is always quick and efficient. The one time an incorrect product was shipped, the company beat a path to my door to get the right item into my hands. Every experience with them has been 100% positive. Great folks!

Mighty Cord Trailer Connector Adapter - 4-Way Flat to 7-Way RV Style - 12" Long
This is my second order with etrailer. Both experiences with your company have been very positive. The knowledge and friendliness -along with following up on orders and satisfaction have been much appreciated. Brittany, the customer representative, is a huge asset to etrailer.
Exactly as described and what I needed. Delivered quickly.

Adapter 7 Pole to 4 Pole with Tester and Cover
ETrailer had exactly what I wanted at a fair price. Website was easy to navigate and purchasing was simple. Shipping was fast and I was kept notified right up to when I received my order.
Plugs in easily, shows that pins are producing voltage, and locks in place using the spring loaded door to the 7-pin.

Wesbar 4-Pole Flat Connector w/ Jacketed Cable - Trailer End - 4' Long
Heavy duty plug that has a good snug fit and I like the jacketed cord that provides strength and extra protection.
I have been very pleased with etrailer orders recently. Everything shows up when expected and products are as expected. Attached are a couple before and after pictures of my recent project to add lights to a cargo rack per my wife's request. Thanks for the professionalism of all at trailer
