4-Way trailer harness connects to your tow vehicle to control trailer light functions. Wishbone-style harness comes with 2 tail light wires split for simple wiring.
This worked great, had to rewire my trailer after having it painted and reconfigured and this item was long enough and allowed me to tie in my additional lights.
I purchased this to update my very old and non-functioning pontoon trailer wiring. I needed the extra length and was glad etrailer provided it as an option. Since the new wiring harness was already set up to run each side separately, it made easy work of rewiring the trailer. I really like etrailer products. I think they are of good quality for a good price. Sorry, no photos of the job.
Lauri - 05/18/2021Wires installed easy and worked for a couple of months. After getting the boat ready this spring I noticed that despite using watertight shrink wrapped and liquid electrical tape sealed connections the wires had completely corroded and now need to rewire the trailer all over again.
Good quality products, and very fast shipping. I have trusted e-trailer with past purchases as well. This order included led tail lights and wire harness for my pontoon trailer. I needed a 35 foot harness and e-trailer had it. They are very difficult to find. And the lights and wiring was first class. Also e-trailer provides good videos for product instructions. Great company.
Steve - 10/09/2020I want to thank you for all your help with my trailer you were more helpful than you realize. So this is my trailer for a 22' Flats Cat shallow draft Catamaran. I totally dismantled my trailer and buffed by hand with a wire buffer and sand blasted in some spots and applied multiple coats of some very expensive galvanize paint (Z.R.C.). I installed all new C. E. Smith Carpet (about 80'), seven new LED waterproof lights, new springs, new equalizers, new tongue jack, new wench, new safety chain, new chain brackets, all new SS hardware and a 35' long wiring harness. I was able to send only one review with a picture of the safety chain and brackets. I'm having a little trouble with the rest..oh some of these items were bought locally or from your competitors, until I found ETRAILER. Your prices were cheaper for the exact same things. Your helpful how to videos were helpful. And Rose, your personal helpful knowledge made my buying experience very pleasant, I actually enjoyed talking to you! Thanks to ETRAILER and specifically to Rose G.
As usual etrailer bales me out. I had a hard time finding a light kit with a 35 ft harness. etrailer had a harness for a great price and if course great customer service to go with it.
Works great. Had to lengthen the ground wire about 2 feet to fit through the length of the trailer tongue; but when fully installed, all the lights including side lights worked.
Raymond M - 01/11/2021Perfect! Just what I needed!! I could only find a harness plug with one brown wire (4 wires total) at my local stores. I "googled" the problem I had (my harness plug had 2 brown wires). A rep from etrailer had answered someone's same question on a message board. It was a detailed explanation as to why one would need this part. Then the rep put a link to the etrailer site. And there is was, the harness plug with 2 brown wires (5 wires total) and at an agreeable price to boot!!!!! And now I know about the etrailer website!!!!
The plug looks and feels solid! This is the only place that had a long enough wiring harness to do what I needed. Shipping was also very fast!
Eric - 01/29/2019Absolutely Fabulous! Exactly what I was looking for but couldn't find at any retail store in my area! The wishbone design splits the brown wire at the plug. Makes wiring both sides of the trailer with no splices or having to find additional brown wire sold by the foot!
I had a 16foot flat trailer that had multiple broken wires and a defective flat plug with a broken ground (white) wire. I decided to completely rewire the trailer and add a couple of lights on each side near both fenders and a 3 light row on the back. The trailer is about 19 feet long counting the tongue. This harness was perfect! The wires were plenty long enough and split to go down both sides of the trailer and wire new lights on both sides and the rear (including new brake lights/turn signal lights). I was a complete novice at this but the etrailer website videos and explanations completely enabled me to do it myself.
After chasing gremlins for one whole summer, I decided just to buy a new harness. This harness was just what I needed. Now all of my lights work and I couldn't be happier.
Makes rewriting trailer very easy Shipping is fast and price is good
Project is ongoing. I ran both harnesses. Together they will light the tiny home. It is 98% finished. I had a 10 month setback. I'm a critical care charge nurse. Covid took me out. I've just gone back to work. Now painting. Next, flooring.
The product is good quality and works fine. What I don’t understand is why it takes so long to ship and receive your order. I placed the order on the 12th, it didn’t ship until the 16th and I received it on the 19th.
Appears to be a much more durable wire than what I pulled off of the trailer I was replacing this with. (24 ft Pontoon Boat Trailer). Old wire had corroded and just snapped, but this feels much better and is a thicker wire and insulation than what was on it.
Excellent product and shipping! Let me say all I could find everywhere was 25 ft. The extra 10 feet I get with this item NOW allows me to fix the short in my utility trailer. Thank you so much.
My wiring was trashed, this harness is a perfect replacement.
Great product. I order mine over a year ago and it still operates fine. I do a lot of saltwater fishing, so of course the wiring is subjected to saltwater. I'm very happy with the durability of these wires
The harness worked well and was easy to install. It makes home repairs much easier and the price was very reasonable. We would recommend this product and intend to buy another to rewire another trailer that we have.
Once ordered the product was shipped immediately. I was pleased to have the product within days even with the economy shipping. I believe this is the first time I have ordered anything from a trailer but have shopped on their website often just to get an idea of what is around. Overall an excellent experience…
I am a fleet manager and have used etrailer.com exclusively for all of my trailer parts needs for repair and maintenance for many years now. They literally have everything I have ever needed and the price is right.
Worked Great for Road King single axle trailer
Shopping online was easy. Site is user friendly. I placed my order on Saturday and received it on Monday. Will be shopping etrailer again for all my trailer needs.
Great service, the mail was a little slow in delivering the product but no fault to etrailor. Will order again
