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.
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.
Brooke M - 09/13/2021Exactly what I needed for my boat trailer. Quick delivery no issues
Very happy with the quality of every item I ordered and its not CHINA JUNK, thank you!!!
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.
Order was correct and timely Thank you
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?
The four prong connector received was to replace a four prong connector which had brown split from one terminal and white split on the other terminal. The result was I had to split the white further down and also split the brown further down which was very difficult. Prefer to have the split white at the terminal connector along with the brown split terminal at the connector. great delivery and also great communications with the receptionist .
East to install
Harness wires were bundled as stated and harness went into trailer a frame without issue.
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.
Great service wuick shipping!
Andy was a GREAT etrailer rep. Everything went smoothly. I have used etrailer several times and recommend them.
Nice heavy gauge wire, stripped cleanly without wire breakage at connectors.
Exactly what I needed and shipping was fast!!
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.
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.
Good product and fit my tandem axle boat trailer. Most places only stock the 25’ option which will not complete the job so etrailer proved their expertise once again. Thank!
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!
No problems
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.
Product just arrived. Looks and feels like a quality wiring harness.
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.
I probably will return this since the fuse was the problem and not the wiring. However, I have no doubt it would be an excellent product just like everything else I got from etrailer!
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.
