Adapter 4-Pole to 7-Pole and 4-Pole
Chose this unit over the one that came with the Universal Kit. Just because of looks are ease of use nothing wrong with the kit. Easy install very simple if you are handy with wiring and connecting electrical.
Superb quality product. Silly simple installation. Took about 1 hour. Received product within a few days as promised. etrailer is excellent and highly recommended. No need to waste time shopping other sites.

Adapter 4-Pole to 5-Pole Trailer Wiring Adapter - Shorter
Works perfect no problems with hooking up the wire to to the back up light...perfect adapter .
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.

48" Long 4-Pole Loop with Cover
it worked well, thanks for a quick response
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.

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.

Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter w/ 4-Way Vehicle End Plug
This, and everything else I ordered from etrailer came without a hitch. They also provided great customer service, answering my question about another product in a timely and complete way.
Worked out pretty good. Had a hard time figuring out just how to attach it. I ended up just zip tieing it. It was a life saver that I could pull the rear plug apart. Made it possible to slide part of the harness thought a tight hole.

35 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 42" Ground
Extremely fast shipping, excellent quality. Will remain a dedicated customer and recommend to others.
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 6-Pole to 7-Pole Trailer Wiring Adapter
I was needing a trailer wiring adapter for my 2001 Dodge 1 ton with DewEze bale bed which has a 6 pin round electrical plug and my PJ trailer has a 6 pin flat plugin connector. I could not find one locally and nobody had any knowledge about these. I found etailer website but needed help figuring out what adapter I needed, Jameson C replied to my email with information I needed. Placed my order and received adapter in 3 days. Plugged it into truck and trailer and it works great. Thanks Jameson C and etrailer. Very good customer service. Good price and received quickly. Will definitely be a repeat customer.
Excellent solution to transition without having to install new connection. Huge Savings. Bookmarked etrailer.com for all my trailer shopping needs. Super fast delivery. 5 Stars

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.
After a year doing its job well.

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.

Wesbar 4-Pole Flat Connector w/ Jacketed Cable - Trailer End - 8' Long
Really quality piece. Plenty of length to connect back to the rest of my utility trailer wiring that was still in good shape since it was in an area subject to far less abuse. Nothing worse than having to fix the corroded wires in between replacing the worn out plug every few years. This should give me years maintenance free service even with the toll winter takes.
This is the 2nd one of these I have purchased. They are a good product (therefore the 2nd purchase) but have a few areas that could be improved. 1) In cold northern winters (MN -10 F), the cable gets very stiff, because of the lack of flex, my trailer connection pulled out when turning, dragged on the ground and ground down the plug. 2) the connection where the cable jacket meets the plug separated (again, due to cold weather?). Even though I would prefer a more temperature-forgiving flexible cable, I believe this design is better than the other 4-flat trailer-end wiring harnesses currently available. I also purchased a Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector w LED Test Lights - Trailer End to as a quick fix to this cable to temporarily fix my trailer wiring until permanent repairs can be done.

Bargman 7-Way, RV-Style Connector w/ 6' Long Coiled Cable - Trailer End
I had to replace the old 7 wire cable because the male plug had been pulled off. I chose the WH54006-043 coiled cable. I used a 1/2 inch clamp to hold the cable up at the box and a Connect-to-Protect to hold up the male plug. The result Is clean and tidy. Thank you,
This should work great, installation is still on my to do list.

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!
Harness is made well. Installation was vey easy.
