Hopkins Active Tail Light Converter with Install Kit
I have ordered from Etrailer several times over the years. Always have exactly what I need. Good prices and fast shipping. Could not be happier. This wiring harness was perfect. Installed it in a few minutes. Thanks.
Excellent. The only down side for my Lexus RX300 was not having an “easy” way to mount male 4-way next to hitch rather than stowing it beside tire bay. No big deal just a plus.

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!
i had to replace these two items as my dear daughter went down our goat path driveway too fast. they replaced the originals from etrailer from the prior year. shipping is timely and customer service actually helps! i wired from battery to controller to hitch myself, and everything fit.

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.

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.

20 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 30" Ground
Trailer wiring got here just today so I can't really review this one. However, I have purchased the same unit before and it's really great. Just make sure you ground it properly and make good connections and it will work fine. Thanks again for a great product and rapid service. Robert
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!

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.

Pollak 6-Pole, Round Pin, Plastic Trailer 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 HD, 7-Pole Round Pin Connector w/Cable Guard
I bought this as part of a rewriting project for my 77 Airstream Tradewind. What can I say - it works and it was easy to install. I've never made one of these before but after following some instructions online my problems were all fixed and I had lights and brakes. FYI, if you are using this for a 77 Airstream like myself you will need to connect the wires from the tow vehicle to this connector according to color with three exceptions: The yellow wire from the tow vehicle goes to the black connector on this plug. The black wire from the tow vehicle goes to the blue connector on this plug. The blue wire from the tow vehicle goes to the yellow connector on this plug. If the above doesn't make sense to you now (like it didn't to me) it will make perfect sense once you have this item in your hand. One more note about my installation - I had two problems that I was trying to solve with this. The first is that I had an "SH" meaning a short circuit in my brake lines. This same error showed up no matter what tow vehicle or what brake controller was connected. The second problem is that my running lights would not work on my camper, however when you connected my camper to another tow vehicle using my old 7 pin plug the lights did work. Strange, but we verified that the problem was not in my tow vehicle so the only option would be this 7 pin connector was somehow not working correctly. For what it's worth, the running lights would work on a 1999 Suburban and a 1997 Tahoe, but would not work on my 2004 Suburban. Anyways, I figured that I would at least try to use this item to make a new connector before taking it in for service and lo and behold once I got everything hooked up it all worked perfectly (the brakes and all of the lights now work). I couldn't be happier.
We had a truck that had a male side of this particular plug. We also had a trailer that needed to be wired up with the female side. etrailer had the parts we were looking for. Purchase was easy and the part fit nicely. Wiring was simple we just printed the PDF file easily found online. We did have to do some simple trouble shooting as our old connector had a 5 wire system but we figured it out. We've bought other trailer items from etrailer and have always been happy with fast service and fair pricing.

7-Way Molded Trailer Wire Connector - 3' Long
I've had this in use for over a year and they don't build them like they use to. I use this on a gooseneck trailer and the piece of plastic behind the spade connector for the clearance lights and brakes has melted, allowing the spade connector to lose contact with the plug on the pickup. So the lights would cut off in the middle of the night and would have to wiggle the connection till I could fix it. I have an older Hopkins plug and never had this problem. To fix the problem I ended up putting pieces of thin copper wire behind the spade and have done it twice since the plastic melted a 2nd time and once again the trailer clearance lights would quit working. Attached are before and after pictures.
The product works great but the color coding is off compared to the colors on the trailer. I started hooking this up matching all of the colors.( Red on Red, Black on Black, etc.) When I plugged in the trailer in it blew a fuse. So I got online and found out that the Hopkins wiring is different then normal trailer wiring. Overall it works great but the colors should match to make it easier to hook up.

Modulite Protector 5-Way Flat w/ Integrated Circuit and Overload Protection
One year review - I installed this on a 2017 Armada. The install while straight forward did require removing some interior panels to access wiring. I have about 15,000 miles of towing a travel trailer on this device and it has worked perfectly.
After another store botched my SUV wiring installation leading to a short circuit and a need to rewire, I found this item for a great price. I wired it myself. It was simple and has worked perfectly with my LED lights and new trailer wiring. Very happy.

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!
I've never really liked Flat-4 type connectors. Unless you leave them dangling, they usually require that you crawl under the vehicle to connect them. (...Murphy's Law dictates that this will always be when it's raining or snowing). This Pollak 4-pole round socket, along with a Tow-Ready harness, and matching trailer connector, provides a neat, factory installed look, that's more convenient, and durable. My orders from etrailer arrived quickly, and with great seller communication. A+

7-Way Molded Connector w/ 10' Cable - Trailer End
As described. Got this one because of the design of the connectors as I’m troubleshooting an issue with wiring. Colors matched the rv-style one I took off my camper. The moulded plug housing is a little shorter than the one that came on the camper so it doesn’t fit in the little storage thing the same way. Functionally seems great.
I upgraded my trailer from hydraulic to electric brakes and rewired everything to neaten and freshen up things. Its a nice piece. I recommend.

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 Endurance 4-Way Flat Trailer Connector - Trailer End - Ergonomic Design
I rewired my light bar for my boat trailer with the items I purchased. Before I built the the light bar, every time I used my boat trailer I would waste valuable sailing or fishing time repairing faulty lights. The do not last long when you submerge them in salt water. This light bar now version 3.0 have given little trouble over the years
Great product. Works well when I had a broken connection on my 4 way plug end on my light-up hitch cover I bought from y'all a while back. Always a happy customer. Thanks, George.

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)

Great product no issues at all. Product as described & fit properly.
Pretty straight forward. I used it to switch my European trailer's connection to be able to connect to my Wrangler's 4-pin trailer hookup. No issues. works great.

Wesbar 4-Pole Flat Connector w/ Jacketed Cable - Trailer End - 14' Long
I rewired my boat trailer using the wesbar 4-flat connector from junction box to the hitch. I do wish the wesbar connector was available in tinned wire. I used tinned 14 ga tinned wire for the rest of the wire and ran a ground wire to every light eliminating the trailer frame as a ground. Also added a switch at junction box for a manual trailer reverse flood lights. Filled the junction box with removable potting Gel to prevent water/corrosion. Works great. No issues. Never been stuck on the side of the road troubleshooting an electrical issue / bad ground. Would purchase this again, unless I could find a marine/tinned wire version, then I would purchase that one instead.
We installed this cord on a tilt bed trailer that we use to transport scissor lifts. We have multiple trucks that pull this trailer and the receptacle on these trucks are in different locations. This required using a 4 flat extension on many of them and as you would expect, the extensions come up missing and of course no one knows what happened to them. We tried every trailer supply store in the Phoenix area and no one carries a cord like this. Because this one is 14' long, we can cut off what we don't need and wire it into the J-box on the trailer and make it long enough that we don't need an extension. Great product.

Pollak 5-Pole, Round Pin Trailer Wiring Socket, Concealed Terminals - Chrome - Vehicle End
The pins were too big by a little bit. Had to force the female plug into the socket
Nice product. Proper di-cast with chrome finish...not the cheapy plastic one this replaced. I prefer this to the flat-4 plug, because the flat-4 can't really be secured the the vehicle, and most of the time thay are run out the truck over the bumper. I didn't want to risk scuffing the painted bumper cover, plus I have a 3rd brake light on my trailer, which requires a dedicated brake light wire. I installed this on a 2006 WRX and a 1990 Mustang (1 trailer, 2 cars that tow it)
