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.

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 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.

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.

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.

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.

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 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.

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!

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.

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.

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.

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.

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.

Hopkins Endurance 7-Way Trailer Connector Socket - Vehicle End - Ergonomic Design
I do not recommend this product. I bought this for my truck. It seems to be the nicest looking plug on the market but after the first rain, the plug was filled with water. I changed the location from the hitch to the bumper and once again the plug was filled with water after it rained. This condition will obviously lead to terminals corroding and/or wires being shorted out. I have bought a different style plug, unfortunately the same brand but hopefully I will have better luck. May be able to drill a small drain hole in the casing to allow water to escape but shouldn't have to do this on a new product.
I bought this socket for my 2006 Volvo Xc90 to wire in the 4-Pole harness I also purchased from etrailer. Already had a few 7 Blade to 4-Pole adapters from my previous vehicle, and wanted the option of adding a trailer brake wire for a small camper later on so that was the main reason for the purchase. It also went very well with the Hidden Hitch I had already installed, bracket mounted right up to the existing tabs on the hitch. Super quick and easy install, as all of my etrailer purchases have been. Looks great on the truck, and functions great with the 180 Degree cover.
