So, I converted my brand new Loadrite trailer to LED'S and wanted to add up a reverse light. I purchased this 5 wires trailer light harness to do the trick. Very good quality and the color code stayed the same. Had no problem what so ever and was an easy swap. I soldered every wires and protect them with heat shrink tubing and that should last a very long time.
Thank you.
This company is my number one go to for trailer needs.

Thanks Ernie, we're glad we could help!!
Works very well. Ran the wires down the tubes of my boat trailer and installed the tail lights and runners very easily. Cut the excess wire off and lights are solid after one year on my boat trailer.

So glad to hear that, Derek! We just had a tutorial here at the office and I was blown away at how straight forward it can be. What do you haul with the trailer? Anything fun?
I purchased this set to rewire my race car trailer and add reverse lights to the pigtail... wiring went flawlessly and there was plenty of wire and connectors are good quality... even had a dog chew on the trailer end and other than a slight ground issue, works perfectly.
25 ft 5-way wiring harness (auxiliary 5 ft Blue wire - backup lights for my application when vehicle is in reverse). This was excellent for me to use to make my boat trailer lights (with addition of lights / backup lights on guide poles) work. Very Easy to wire up.
Got this wiring harness for my small camper to completely re wire it. Also got rheTLl28RK combination trailer lights. Nice and bright!
Easy to install perfect length and works great!! Can’t see it on the trailer because I have it heat shrinked and wire loomed for protection
5-wire harness kit is exactly what I need. I hate splicing wiring runs because, in a saltwater environment, this only leads to more chances for corrosion. The only thing that would be better is the complete round plug set-up.
My boat and truck are happy!
I installed this on a Moomba boat trailer and it fit perfectly. Installation was easy enough. Paired with e-trailer's submersible LED trailer lights, the parts went together for a seamless, durable system that will last for years to come. The boat trailer looks like new again! Thanks e-trailer!!
Item is just what I need to rewire my 99 Triton boat trailer. Item is of great quality and at a competitive price. In addition,the item was shipped and delivered fast. Lastly, staff members are courteous and willing to assist with any questions and concerns before ordering and upon arrival. I will definitely do business with in the future.
Just as described, good harness at a good price.
Average quality, very good shipping time plus hard to find item but etrailer had it.will definitely be buying from you guys in the future.
Very high quality wire, easily stripped outer and very good quality copper wire within. All connections were spliced and soldered, covered with heat shrink.
Easy to use. Again, having back-up is a game changer. Long overdue and nice to have affordable quality product to upgrade with.
This product was exactly what I was looking for. I was having issues with my trailer lights on a 20 year old trailer. I decided it was best to just remove all of the old wiring and start off new. This product took care of any concerns i might have had by just replacing a wire or two. All of the lights and connections are excellent and I don't worry about something not working.
After having this in my garage for about 6-9 months I finally got around to rewiring my trailer with this harness. The harness has been on the trailer for 4 months and it has been solid. I would recommend getting longer than you think you will need. IE if you have a 25 ft trailer get a harness that is ~30 ft.
Wiring is great. Was given 2 truck tail lights with back up lenses so I needed to rewire my trailer for a 5 wire system. My trailer is 30 years old so it needed a complete makeover. e trailer was a great help. They had a 5 wiring harness and a duel trailer connector for my Jeep. I needed a 4 wire and a 5 wire adapter to fit the Jeep to 2 trailers I own. They had what I wanted and it was delivered in 3 days.
This wiring is almost plug and play! It is already set up with double brown wires to meet today's trailer wiring standard. And with the hitch-end flat plug and ground ring already in place, it is a quick installation. Thanks.
Great, I think I will enjoy the install, with all that's going on in the World. Thanks for the extremely fast delivery and help with making my selections!
I did make one mistake, the Thin LED Light I order; I think I need to order the base bracket as well!
Fast shipping and great product. Easy to install on my boat trailer. Will test the longevity of this product over the next several years. But overall very pleased, and etrailer is a wonderful company.
Needed to replace my wiring on my 18 foot boat trailer. This did the job. Easy plug and play.
I have been in sales, retail, B2B, and sales management for over 30 years. E trailer has the whole package - excellent customer and sales service, great products, videos for those of us who like to do our own work, fair prices, and my go-to for my trailer needs.
Well made product easy to install.Delivered in 3 days,with free shipping as I ordered it with a few other items.Priced very reasonable. I am very happy with my order.
I. ordered this along with marker lights its been a year and they work great.
Product works well. Installed on boat trailer used primarily in saltwater. Corrosion is minimal.
Part was not in stock but company stayed in close communication until I received my order. Very pleased with this company in other orders as well.
