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.

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.

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.

7-Way Molded Trailer Wire Connector, 4' Long
When I ordered this harness I thought I was getting a standard 7 way for a conventional trailer with brakes. What I actually got was a harness made for a camper/RV hook up. The wires have all the colors you would expect but all the lights/turn signals are coded into the plug completely different. After spending a good deal of time carefully matching, soldering and heat shrinking all connections to my new trailer harness, I was very dismayed to find only the brakes actually worked. After a bit of research I found a schematics page on the etrailer site and discovered the problem. As this is a molded plug I could not take it apart and just reposition the wires inside the plug. Another full hour or more of rewiring followed and now all is well. The harness itself is of very good quality but was not labeled/identified properly. This could have been prevented if etrailer would clearly label this harness as a camper/RV harness only.
This is definitely a good quality molded cord for the money. Route and wire this cord into a good quality junction box and you will be on your way to having some excellent trailer wiring.

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.

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.

Hopkins Trailer Connector Adapter - 7-Pole Round Pin to 7-Pole RV
Product won't work correctly. I've tried it with 2 different trucks and 3 different trailers. Each Turn signal will active the hazard lights, and no tail lights. When pressing brake lights, all side marker lights will light up.
Brake doesn't work locks them up

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

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

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.

Hopkins Endurance 5-Way Flat Trailer Connector - Trailer End - Ergonomic Design
The product arrived in a timely manner and undamaged. I have not used this 5 pole adapter yet, but the 4 pole adapter I previously bought from etrailer years ago is still working great. I have no reason to doubt that this adapter will function equally well. I appreciate the good products and customer service from Etrailer.
I needed the extra wire to run for multi-led lights mounted underneath the steps at the rear of my trailer, when in reverse trailering. This connector seems heavier-duty compared to many on the market and so far is still working well after a year or more. As with most products from etrailer, I haven't been let down yet. Here's a real special GOTCHA moment I had recently; My trailer jack stand, which I had purchased from my well-known and popular local trailer company to replace my original had rusted to pieces. I needed a replacement quickly and trusted I'd get a decent product and price as had been the norm over many years. Anyway, I purchased the new jack and wheel and brought them home to install myself. Upon taking the jack out of the bag it came in, I noticed a sticker from etrailer, yea. Before installing I went online, saw that my jack was less than half the cost I'd just paid, and realized I should have purchased the jack when I had originally shopped online at the start of this replacement process. I could have returned my over-priced items but decided I didn't have the time due to procrastination. I decided they could keep their extra profit on this purchase but I won't get fooled again and my local shop has lost my trust.

Hopkins Wiring Harness with 5-Pole Flat Trailer Connector - Vehicle End - 5' Long
The Glolight LED trailer set is the perfect replacement for my tow dolly. It is light weight and much more visible than the standard bulb lamp set the trailer was equipped with. Installation was quick and very easy, I will recommend this to all needing to change theirs out...
Great Prices and Fast Shipping

Hopkins Endurance 5-Way Flat Trailer Connector - Vehicle End - Ergonomic Design
I fitted the Hopkins 5-way flat connector harness with a 5-way round plug which couples to my Goldwing trike (tow vehicle). The popup trailer lights operate as designed.
Connector and wire harness well made - connector designed such that it can be mounted and harness has added protection for wires. Would like to have marine grade wire since I do mostly saltwater fishing. I mounted the connector on a piece of 1.5" square galvanized tubing painted black.

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.
The items I ordered will allow me to adapt my utility trailer for transporting my sea kayaks. Curt and Hopkins are both quality manufacturers. On a shipping note, the box arrived at the Post Office broken wide open. Your shipping folks need to wrap small, heavy, items in bubble wrap. Then stabilize it with foam peanuts. Just putting it in a box then stuffing the box with craft paper does not cut it. Items were not damaged so I am good to go.

Hopkins Wiring Harness with 5-Pole Flat Trailer Connector - Trailer End - 18" Long
Good for converting 4 wire boat trailer harness to 5 wire. I would have preferred an adapter that plugged into the existing 4 wire plug with an integrated backup wire that is spliced into the blue wire on the trailer.
The whole staff at etrailer bent over backwards to make sure I was satisfied with the installation of brakes on my trailer. Have made several purchases from them always satisfied with parts and service. Special credit to Jamie great to deal with. Answered all my questions and was very knowledgeable.

Hopkins Endurance 4-Way Flat Trailer Connector - Trailer End - Ergonomic Design
Shawn B. (& everyone I talked with at E Trailer) was wonderful. Great phone support. Great products. We did a great job installing the wiring harness. Made me wonder why we originally took it to a "professional" trailer sales & service place in Ogden UT. They hacked into our wiring & created problems. I will continue to be a grateful customer. Finding good people who know their stuff in todays world is a soul healing event. Thank you E Trailer!
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
What our customers are saying:
"very good seller, very good product, fast shipping thank you"
