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.

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).

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.

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 7 Pole to 4 Pole with Tester and Cover
I have ordered several adapters and complete trailer wiring harnesses from Etrailer. All have been top quality. I have saved a lot of money on the plug and play trailer harnesses. Several hundred dollars when they are factory installed, less than $75 from Etrailer.
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

Hopkins Heavy-Duty Trailer Coiled Wire Adapter for 7-Way to 4-Wire Flat
Item was just as I anticipated. It looks good, works great, and the delivery was as promised. E Trailer is a good place to do business.
Works, exact fit, high quality, coils tight so max of about 3.5’ perfect! Heavy duty wiring, great waterproof connections.

Pollak Black Plastic, 7-Pole, RV Blade-Style Trailer Socket - Vehicle End
the wiring for my Tacoma was correct color for color. However, the plug from my Tracker boat would not engage. I had to disassemble the socket to find out the contacts were bent too far towards the center of the socket. I bent them out a bit and everything is good.
Used this for a 12V power supply output, not connected to a trailer. Works.

Adapter 4-Pole to 5-Pole Trailer Wiring Adapter - Shorter
Super quick delivery and great CS helping me make decision. Love you guys.
I had a 2 inch trailer hitch and 4 pole flat wire harness professionally installed on my 2001 Dodge Ram Pickup. When I bought my boat the trailer was wired for a 5 pole flat harness. Took my truck back to the installer to have the harness exchanged and was told that there was no 5 pole flat harness made for my 2001 truck. I asked about splicing a 5 pole flat harness to the 4 pole flat harness and was told by the installer that they don't do splicing and because the 4 pole harness was already installed I couldn't get a refund. So the search was on to fix this problem. Stumbled upon the etrailer E-commerce site and found what I was looking for. A 4 pole flat to 5 pole flat adapter. The price was right, the service was 5 Star and I received the adapter in 4 days which was perfect. I had time to install it, and get my boat on the water that weekend. Thanks George J. I will be using etrailer for all my trailer needs.

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.

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 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.

Pollak 6-Pole, Round Pin, Plastic Wiring Socket w/ Rubber Boot - Vehicle End
Used on tow vehicle for hooking up wiring harness to motorhome
This part is an exact replacement to the part that failed. The failure was caused by a poor installation which allowed the rubber boot to chaff on the truck frame. As it was an exact replacement installation was straight forward although I modified the mounting bracket to prevent a reoccurrence of the problem.

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!

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.
Product so far has worked great for a pinched/cut OEM 7pin cord. It isnt weatherproof like an OEM connector to the cord-as well as the female end of the connector but then its just the connector so totally sealed is not the design for this. It works fine & currently has saved me from having to purchase a connector & wire cord as 1 piece & some shennagins with installing that set up.

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.

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

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 Heavy-Duty, 4-Pole, Round Pin Socket, Concealed Terminals - Chrome - Vehicle End
Wiring harness and flat tow bracket to be able to tow our new Wrangler behind our motorhome. Product arrived on time and everyone was most pleasent to deal with. had the bracket installed by the dealre we bought the Wrangler from as part of that deal and then did the wiring ourselves. Pretty weasy thanks to the excellent video provided by etrailer and it took us rookies about 3 hours to complete. we are very happy with the service and product. Thanks to all. Regards,
Product arrived on time and as described. I used this for setting up our 2014 Wrangler Unlimited Sahara for a flat tow. Mounting hole spacing @ 2" o/c didn't match our Blue Ox 1126 draw bar so I fabricated my own intermediate bracket, polished it to aircraft tooling standards, then lacquered it before final assembly. I think the finished product came out nice.

Wesbar 4-Pole Flat Connector w/ Jacketed Cable - Trailer End - 4' Long
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
Delivery was quick and electeical was just what I was looking for. Was able to mount bracket to hitch and running the wiring was easy with it all color coded. The single sheathed trailer plug was also what I was looking for and priced below anywhere else. Was very industrial and was almost an exact match to replace the existing one on my triton trailer.

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.
