This wishbone-style, 5-wire flat harness is great for a trailer with a surge coupler. The 40' long harness includes a 4' long ground wire and a blue auxiliary wire that signals your trailer brakes to disengage while you are in reverse.The product was exactly what I ordered. For the few people who complained the blue wire is shorter than the other wires, the blue wire is only going to the surge brake. I do wish someone would create a wiring harness that is fully tined like other marine wires. Trailers that go into salt water, operate near salt water or travel on salted roads get plenty of opportunity to corrode. I plan on using heat shrink connections for my boat trailer. It takes longer, but will last longer. I'm also installing rubber grommets to keep wires from rubbing against metal edges.
Good wire harness. Good quality and still working great after 1 year.
The wrong item was shipped. I called and spoke to Eric who immediately handled my complaint in a very efficient manner and was having the correct item shipped out. Thanks Eric.
I wanted a heavier gauge when re and this particular item is perfect. I did an ohms test and voltage test on the product and it works perfectly and craftsmanship is excellent. Highly recommend this. I can’t provide pictures of install right now. I’m in the process of doing a complete make over on my boat trailer. Repaint, new lights, new brake lines and rewire.
Excellent product, excellent service!
Arrived exactly as advertised.
Use on salt water trailer and have no issues or sign of the slightest wear.
Being used in saltwater I did not want connectors so one continuous wire was required. At the time this was the best price and value.
The blue wire was supposed to be 40 feet like the rest of the wires, the harness that was sent has a 5 foot wire which does me no good as it doesn't reach the lights it's supposed to operate. I’m really frustrated with “American” companies that claim to be superior to others and yet they can’t get a simple order right. I had to order this set up because the so-called 20’ wire that I got with my light kit wouldn’t even go the entire length of a 12’ trailer. The 5’ wire does me NO GOOD as it doesn’t reach the lights that it’s supposed to operate. Please explain to me how you’re going to rectify this “made in Mexico” product foul up.
Simple replacement to trailer existing wiring
I completely rewired my boat trailer after patching it for several years because mice and chipmunks were eating the insulation. I installed the product in aluminum flexible metal conduit inside the trailer tube frame. So far so good. The little critters have not been able to get to the wire insulation to chew on it. The plug is well made and seems durable.
I purchased this and several other products from etrailer.com to wire my 2020 Jeep Gladiator. I did cover this with aftermarket braided line covers. It was long enough to connect to both rear harnesses. I purchased this or a similar product from etrailer in the past and always get a quality product at a reasonable price.
No complaints
All ordered items worked great. Love the LED tail lights. Didn't have any problems fixing the trailer thanks to the many technical articles I found on etrailer. Not sure what happened with UPS shipping since I got notified that the parts had shipped on Saturday but didn't get them till Wednesday evening (paid extra for 3 day shipping), but definitely recommend ordering from etrailer.
As good as the day I bought it ... since it is still in the original packaging. Purchased it for my boat trailer, project #34 on my list of things to do. Still in the 20's. However, quality, length, materials were exactly as ordered. Will follow up when installed - don't hold your breath!
Reasonably easy to replace. Issue was doing it in cold weather, while doing other work on the trailer.
One issue was the ground which failed as the tongue was not securely attached to the rest of the trailer. Once recognized the system worked perfectly.
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.
It did the job. Quick delivery and as d escribed
I will never understand that if I am purchasing a 5 pole harness in a 40' length, WHY would they only give me a 5' lead for the back up wire when I want the lights at the back of my trailer?
Nice heavy gauge wire, stripped cleanly without wire breakage at connectors.
Harness wires were bundled as stated and harness went into trailer a frame without issue.
Exactly what I needed for my boat trailer. Quick delivery no issues
Great product. Worked very well for my boat trailer. Made installation of my new LED's a breeze.
Perfect wiring setup for running a 5 wire plug with a backup light wire. Being able to run down both sides of the trailer is exactly what I needed.
Exactly what I needed to rewrite my boat trailer that has brakes-
Exactly what I was needing/looking for to rewire my trailer and at a great price too! Shipping is very reasonable. Will definitely do business with E Trailer.com in the future as need arises!
It was just what I needed to replace my patched wiring on my bass boat trailer. I ordered the longer set so I was sure it was long enough.
