Pollak 7 Pole to 4 Way Connector Adapter
a perfect solution for towing a U-Haul trailer when you have the wrong electrical hook up. It looks built in with no dangling wires.
Perfect match for Twist-in, 7-Pole, RV-Style Trailer Connector for Nissan Titan. I'm satisfied it, so far I haven't had any light out on the trailer due to connection. Thanks

Hopkins Endurance Multi-Tow Trailer Connector Adapter - 7-Way to 6-Way, 5-Way or 4-Way
My '92 GMC Sierra had a 6-pin trailer harness connector and I'm going to be pulling a pop-up camper in a few weeks that has a 7-pin connector. I originally ordered a 47435 6-Pole to 7-Pole Trailer Wiring Adapter. After thinking about it for a day I changed my mind and ordered a HM48470 Hopkins Endurance Multi-tow 7-way, 5 & 4-wire Flat Connector to mount in the bumper and a HM47570 Hopkins Endurance Multi-tow Connect Adapter - 7-way To 6-way, 5-way and 4-way. The HM48470 will allow me to pull the pop-up as well as giving me the 4-wire flat connector that I need for my boat trailer. I bought the HM47570 adapter just to cover all the trailer wiring needs I might run into. I really like the fact that the 47570 adapter has the quick change plug to cover both wiring arrangements for 6-pin trailer connectors. I placed the original order Saturday evening and the second order Sunday afternoon. Monday morning, I called etrailer.com to try to cancel the first order and was told that both orders were already boxed and on the way the shipper. I had no idea that they had people there to pull and box orders on the weekend. I asked about returning the first order when it arrived and was told by Helen M that it would be no problem at all. I have been extremely pleased with my purchase experience with etrailer.com. Everyone I spoke with there was very knowledgeable and I will not hesitate to go directly to them for my trailer and towing needs in the future.
I needed an adapter for my electrical towing harness so the that I could use a 5-Way connector on my 7-WAY plug. On line, I found and ordered Item No. HM47570 "HOPKINS ENDURANCE MULTI-TOW CONNECTOR ADAPTER - 7-WAY to 6-WAY, 5-WAY or 4-WAY." When I received the product, I was really stoked, it was exactly what I needed and what I had been looking for! I tried it on for "size" as you might say and it's going to work like a charm. I will send some photos later when I'm done with the installation! No time right now. . this coming weekend! Photo 1&2 my connector; Photo 3&4 the new HM47570; Photo 5,6,&8 the light bar I wanted to install and the completed project. Thanks a bunch!

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.

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.

Hopkins Endurance Multi-Tow Twist-Mount 7-Way RV and 4-Way Flat Trailer Connector - Vehicle End
It was exactly what it said it was. Perfect replacement.
My original equipment had reached its life. This allowed me to get rid of a 4-way to 7-way connector.

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

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.

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.

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

Reese Trailer Connector Adapter w/ LED Circuit Tester and Dust Cover - 7-Pole to 4-Pole or 5-Pole
Works well and makes checking the circuit easy. Helps determine if a problem is on the vehicle side or the trailer
I bought a cheaper one at an auto parts store and had issues with it not connecting consistently. This one works 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.
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).

Hopkins Heavy-Duty Trailer Coiled Wire Adapter for 7-Way to 4-Wire Flat
Works, exact fit, high quality, coils tight so max of about 3.5’ perfect! Heavy duty wiring, great waterproof connections.
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.

Hopkins Endurance, Flex-Coil Trailer Connector Adapter - 7-Way to 5-Way or 4-Way Flat with Nite-Glow
What a great product!
Great product. We used it with our Toyota 4 runner to tow our boat. Since the Toyota 4 runner electrical plug in is so far behind the rear bumper, we needed this extension in order for there not to be any issues with the wiring for boat trailer to become disconnected from being too short. The cord being coiled allows the extension to be as long as needed without possibly being drug on the ground.

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!

Hopkins Heavy-Duty Trailer Coiled Wire Adapter 7-Way to 5-Way Flat with Nite-Glow
Still works great. The light up feature is great for knowing if a lighting problem is the vehicle or trailer.
The yellow wire coating is cracking and flaking off.
