Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector
I received this purchase and was installing it the next day. Luckily I read the other reviews and saw that I HAD to attach the white ground cord that was sticking out of the harness. Upon looking, I found the white wire that comes out out of the flat 4 plug isn't attached to anything thus requiring the ground to be attached to the vehicle. All in all, I was very satisfied with this purchase.
Fit right, plugged right into existing wiring harness, worked fine.

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)
Very easy install. My truck had a precut hole in the bumper for the plug. I then hooked the spare 4 pole plug into a Reese Universal mounting bracket and mounted it onto the hitch.

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 7 Pole to 4 Way Connector Adapter
This product has been great. I purchased the multi-pin trailer wiring kit, and 4-pin adapter plug. By also purchasing the vehicles specific wiring harness, instalation was quick and easy! I chose to mount this through my bumber, instead of using the included bracket for a more factory finished look, and to avoud ripping off the mount while on rought terrain. This system works great and is much more affordable than factory parts. I highly recommend!
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.

Curt Universal Installation Kit for Trailer Brake Controller - 7-Way RV - 10 Gauge
I ordered this wiring kit for a 2003 Dodge Ram 1500 I recently acquired. The Ram was not tow ready but did have a factory 4-way. I also ordered hitch #13333. The wiring kit is very high quality and was easy to install. The 7-way fit perfectly where the factory 7-way would have gone. I'm using a Tekonsha Prodigy RF wireless brake controller so the blue lead was not needed but I left some extra should that change. Thanks etrailer!
Arrived on time and installing now

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.
Needed a longer connector for my vehicles. Both have 7 way plugs, but I use a trailer with a 4 flat plug. The coiled adapter works great for both of the vehicles. Very good product if you need some extra length and the fact that it has the coils makes for a better appearance.

Adapter 4-Pole to 5-Pole Trailer Wiring Adapter - Shorter
Arrived quickly. I didn’t need to wire the extra lead to my reverse lights because my trailer doesn’t have surge brakes or backup lights. Simply plug and play.
Perfect for converting 4 wire Ford Expedition trailer harness and boat trailer to 5 wire. The Expedition had a backup wire run to the area of the 4 wire plug so made the conversion easy.

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.

Mighty Cord Trailer Connector Adapter - 4-Way Flat to 6-Way Round - 12" Long
Worked exactly as I expected. I’m setting up my Jeep to flat tow it behind my camper.

Hopkins 4-Pole Loop - 12" Long
Perfect product for my needs. My 4 pin is hiding under a cover on my bumper, so I used this device to plug into the vehicles 4 pin and allow the extension to hang below the bumper. Now I can quickly plug in to the adapter without taking a panel off. Cheap easy fix for a great deal of convenience!
I had purchased a Pro Series Cargo Carrier 63153 and the 20174 light kit. Assembly was very straight forward but I found that the 4-pole connector harness was too short. This 12" extension was perfect. Also, Jonathon at etrailer provided excellent customer support getting it to me while on a trip.

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.

Trailer Connector Adapter for Land Rover - 7-Way, Round Pin, European Style to 4-Way Flat
Great build quality, but unfortunately it will not work to legally use a 4-pin trailer being towed by a 7-pin Euro/Land Rover plug. Its simply mapping 4 of the 7 pins to the following pins on the 4-pin side. Left running, Right running, Stop and negative, there is no provision for indicators or dual sided brake lights. It needs diodes (which it does not have) to do this. etrailer just needs to update the description as this is a good basis to make various adapters.
Received product in good order, well packaged, initial some delay, manufacturer was chased by etrailer, and earlier dispatched by manufacturer; delivery trail clear stated, very good. On receiving verified at UHAUL: connect with 1983 Land Rover (Defender) 110 Stationwagon (photo: rear, while on transport): all functioned ok. Apparently some diode(s) included, as the 7 pin has individual stop light which translates as left AND right indicator on flat pin. Emergency flashing (all indicators left and right) tested ok at UHAUL (connecting to trailer). LR has European homologated 3.5 metric Ton (7700 lbs) tow hook and has done some 60,000+ miles towing with current odometer reading 578,000+ km (on/about 360k miles)

What I ordered! Don't need at this time but keeping for future! Because of age of auto it may not be able to get later! Shipping was fast and price was great!
E-trailer: they've got what I need at a reasonable price. This is what e-commerce should be!

Hopkins Endurance, Flex-Coil Trailer Connector Adapter - 7-Way to 5-Way or 4-Way Flat with Nite-Glow
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.
The product itself is of sturdy weight and production. BUT, the product description says 0-5 feet in length. It would difficult to stretch this product to 5 feet and not have it unplug itself on a bumpy road.

Curt Trailer Connector Adapter - 7-Way RV Style to 4-Way Flat - 60" Cord
Very good quality.
Just what I was looking for. Most of these are 36-48 inched. This one is 60 inches. Perfect for 4 down towing.

6-Pole Square Trailer Wiring Connector Kit (Car and Trailer Ends)
Good product. It's what my motorhome came with. Thanks.
Bullet-proof connector, if not the most elegant. Used in my case for custom "adventurization" wiring on my 2007 BMW F800ST motorcycle, now just road tested this late summer - early fall 2017 on a three month, 18,000 mile loop out of Chicago through the Arctic & Pacific Northwest, including the Dempster & Dalton Highways. Had a custom wiring harness that had to be able to be removed in order to get at the engine, hence the need for the connectors. A few photos should be attached.

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.

Curt Trailer Connector Adapter with Backup Alarm - 4-Way to 7-Way RV and 4-Way Flat
I never used it. It does not fit my motorhome. Still sitting in my garage.
Exactly what I was looking for. Easily connected to my existing 4-way without any additional wiring. The 7-way adapter bracket was the correct size, and the holes were pre-drilled for the right fit to connect to the existing bracket on the (U-Haul Installed) tow bar.

Custer Trailer Connector Adapter - 4-Way Round to 4-Way Flat
ITEM ON ROUND END WAS LARGER THAN ROUND SOCKET ON TOW VEHICLE. DIDN’T FIT.
Great product, just what I ordered. I couldn’t find this adapter anywhere else until I came upon it at etrailer.com!! I have ordered other products from etrailer and have been completely satisfied with those products as well. Thanks.
