I would like to really thank the team at etrailer for making my order correct. George, Amy and Carol all worked well with communication with me when there was a small issue with the amount of connectors I ordered. They made things right and I have nothing but appreciation for their work and attention to detail to help me out. Thank you again and I will be doing business again!! A+

Exactly what I needed to rewire a 20-year-old trailer that was starting to show it's age with inconsistent lighting performance and continuity issues. In addition to purchasing this lighting harness, I upgraded all my incandescent bulb side markers and taillights with LED units and complete rewired the trailer. etrailer had everything I needed in one place with excellent pricing and superb service. Everything is working great and I love the brightness and visibility of the LED lights.


All appears to be as described.
impressions are the ones that last. Thank you for the prompt delivery and professional packaging.


Awesome thanks


Just upgraded to a 2016 Odyssey and need to tow my camper.
Purchased the OEM hitch and OEM custom harness (from car to 4 pin on hitch. OEM Hitch comes with nice beefy flange where the 4 pin connector mounts. But I needed a 7 pin for electric brakes and bought this ETBC7 kit to do the job.

I ended up cutting a custom hole in the bumper cover and figuring a way to mount the bracket in this kit directly to the OEM hitch. Wanted to share photos of the install for anyone else in the same boat. Advantage of my install is that the 7 pin is mounted above the bracket, protecting it from injury from low clearance obstacles on the road. One Con, is I had to mount it upside down so it didn't interfere with the metal bumper under the bumper cover.

One issue I remember is that the Ground wire on the 7 pin harness didn't come close to reaching an available frame member, at the side of the car. I had to cut off the ring lug and extend it out to the edge of the car to complete the install. But it is done now!



MUNSTER - 07/13/2016


These work great! Save time soldering, cut-strip-heat!!!


couldn't use the wire connectors, to small for the wires on truck and trailer wiring harness. The trailer hitch fit good and the wiring harness was as advertised. No problem installing either of them


I had trailer light problems (who hasn't?) and found etrailer on the web. The site was extremely well organized and made it easy to find what I was looking for.
I had a question regarding the kind of wire connector needed. It was answered promptly by E-mail.
The lights and connectors arrived as promised and the installation was straightforward thanks to the videos on the site.


Being a new boat owner I was quickly overwhelmed by what I didn't know. Re-wiring, re-lighting my trailer was my first project. etrailer has a wide range of products, but most important to me, was their added product information and instructional information which helped me make the right selections to get this done. Add to that is their very competitive prices. etrailer will be my go to source for my future trailer needs.


Perfect finish to installing a water tight LED light kit on my PWC trailer. These are of good quality and I had plenty to spare.

Still water tight and working, would buy again.

I really like the idea of any outdoor wiring connector that has self-sealing heat shrink. I don’t agree with the suggestion of using a lighter to activate the heat shrink—use a proper heat gun designed for this.


Order was complete and delivered in a timely manner. Only problem (minor) was the 7way pigtail was not wired to color code. Had to use test light to get 3 of the wires in correct location. Could be a problem if someone wasn't comfortable with ringing out wires.


Just received my order of new backing plate assemblies and some misc small parts. Ordered on line late Sunday night, confirmed I had ordered the right parts Monday morning before shipment went out. Customer service by phone was superb and the gal I talked with was perfect. Shipment was on my porch Friday afternoon. I did open box and inspect shipment that arrived completely intact/good shape and all looked good at this point. Not sure when will get to the brakes on the trailer but will post again when the job is done. So far nothing but good to say about Regards, John.


Good product but, too small for brake wiring. You did not have the right size.

We recommend 10 or 12 gauge wiring for trailer brakes. The Deka Heat Shrink Butt Connector - 12-10 Gauge - Nylon Insulation part DW05745-5 will work well for you.
-- Etrailer Expert Heather A - 02/10/2021


Loose boxed. prefer separate packaging. Good product and if your wiring or fixing your wiring, this will work well.


Haven't rewired the trailer yet, but the items ordered arrived quickly and the order was accurate. Great prices and service!

Great! I dont use the bot very much, but all the lights still work!!!!

etrailer did an exceptional job in processing and shipping my order out complete - ahead of projected delivery - hats off to everyone at etrailer - it is a team effort. Thank you for the great experience and I'll check with etrialer on any future needs...…


I was very pleased with my brake shoes. The installation went smoothly. The packaging could have been better. The box arrived in a beat up condition, but the contents were okay.


Great selection and quality products. My order arrived on schedule. No complaints

Ive had the boat trailer in and out of the water several times and traveled over a thousand miles, including hundreds of miles down Canadian logging roads. No problems at all with the connectors coming loose or corroding.
Arby - 05/12/2016


Products very good. Installed easily. Look good and work well. Only problem was shrink tubing way too small to fit over connectors. Otherwise everything fine. No biggie. !!


These butt connectors work like you expect them to and at a great price!


Item was exactly as ordered and of high quality. I had a question as to which of two wiring connections I needed for the lights I purchased. My questioning email was answered immediately and correctly. Good customer service.


Great product. Fit my trailer tail lights perfectly.


They work as advertised...very nice for those under trailer connections...:)

  • Converting 1997 Dutchman 6-Way Square to 4-Way Flat
    Jayco does have their own system. I recommend cutting the harness as you stated and connecting them to a 4-way flat trailer connector to be compatible with your truck. To do this, you will simply need the Hopkins Endurance 4-Way Flat Trailer Connector - Trailer End - Ergonomic Design # HM48110 and a few butt connectors like the Deka Heat Shrink Butt Connector - 22-18 Gauge - Nylon Insulation - Red - Qty 10 # DW05743-10.

  • What Gauge Wire Is Used On the Hopkins Endurance 4-Way Flat Trailer Wiring Harness?
    The Hopkins Endurance 4-Way Flat Trailer Wiring Harness - 20' Long # HM48240 uses 18 gauge wire for the 3 lighting functions and 16 gauge for the ground wire. This is standard size wire for a 4-way flat harness, but the ergonomic grip on the connector for the easy pull disconnection is what sets this harness apart from others. I recommend using the Deka Heat Shrink Butt Connector - 22-18 Gauge - Nylon Insulation - Red - Qty 10 # DW05743-10 for your light connections.

You can use a circuit tester like # PTW2993 to determine wiring function and then use butt connectors like the Deka Heat Shrink Butt Connector # DW05743-10 to make your connections.

  • Is Heat Shrink Tubing Included in Deka Butt Connector DW05743-10
    The Deka 22-18-gauge butt connector 10-pack, part # DW05743-10, already has built-in heat shrink tubing on the connectors so it is not necessary to add it. If you want to add an additional layer of protection from moisture and other contaminants you can apply Deka Self-Fusing Auto Tape # DW04367 around the entire connector after you have applied heat to the heat-shrink tubing.

    In order to join lights together on a boat trailer you'll want to use heat shrink butt connectors like part # DW05743-10, part # DW05744-10, and part # DW05745-10 as they keep out moisture which reduces the chance for corrosion that cause lighting issues. If you need to tie multiple wires together, you can do so using one of the larger butt connectors. In order to seal these connections you also need a heat gun, the Trades Pro Dual Range Heat Gun w/ Nozzles part # ALL836717. I have attached...

  • How to Wire in Dual 4-pole Vehicle-Side Trailer Connectors on RV
    There are several ways to have dual 4-pole flat vehicle wiring on your RV, depending on how the RV wiring is set up. If the RV uses a round U.S. Car connector at the back of its 7-way you could use two of part # 118384 in a daisy-chain set up. This would provide two 4-poles and keep your 7-way active. This is a plug-and-play option. If you don't mind a bit of cutting and splicing you could tap into the wiring that leads to the RV 7-way and splice in two of an item like # HM48030 using...

  • Trailer Wiring Harness Installation Location at the Back of a 2008 Nissan Pathfinder

There isn't a plug in harness or adapter for Nissan vehicles with the 8-pin connector, such as your 2008 Pathfinder, but there is an option for you. First, and what I recommend, is to use the harness you have, # 118267, but cut off the vehicle and harness side connectors and hardwire them together based on function. Use a circuit tester such as # 40376 or a meter such as # PT89ZR to test the wires...

  • Wire Connector Recommendation for 20 Gauge Wire on Trailer
    For a 20 gauge wire I would not recommend the use of a quick splice connector. The core of the wire would be too thin for it to work well. You would most likely end up cutting the core of the wire when tightening it. I would recommend soldering as the best solution and then beyond that butt connectors like the part # DW05743-10 would be the next best solution.

With that being said I highly recommend still testing them each for function for verification...
