Simple and quality wire harness set Needed to rewire a friends trailer w/ an updated set up Easy to use and install for this type of set up 162425
Just fine still working correctly
Mark v - 11/25/2015Fantastic !!!! Great product, exactly as detailed, exactly as pictured, easy ordering, and on time shipment / arrival. I have never wired a trailer before, but after watching the online video program and following the steps I was able to complete the project in a hour for a 14' boat trailer. Prior to ordering, I did a lot of price comparisons in my area and I could not beat etrailer pricing. Great product. 155199
Thanks for the follow up - One year later the products are working spectacular and I keep plugging away at your company - telling all of my friends about it.
Martin F - 10/19/2015It's a simple item but try to find it somewhere else as a stand alone product. I've used etrailer before with great results and this was no exception. Let's be honest, if you've been to the site once, you're coming back! I have a 5 x 12 utility trailer that has good lights but the wiring was a disaster. The harness connector had been patched and there were at least 5 splices throughout the lines. It was nice to lay out the new harness, make the light connections, tack everything up and out of harms way (there's an idea) and my lights work like new. I like the ground fastens under the jack bolt. Saves drilling a screw in (see the baby hole?) Good to feel safe on the road again. As easy and inexpensive as it was, I don't know why I waited so long. 539599

All parts are high quality, always fit as they should and arrive quickly. An email from a person always preceeds and follows the parts delivery. This is why I go etrailer.com, again and again. 636228
Fortunately I didn't need to rewire my whole trailer, but there is plenty of length for a 9 foot trailer with a 4 foot tongue. 634050

Exactly what I needed- matched OEM part 556292
Worked as needed for rewiring trailer. Holding up nicely. No signs of deterioration yet. Ground wire wasn't quite long enough to reach original connection, but was no hassle to move. 554195
Exactly what I needed to begin rewiring a trailer. My sons cattle ate the trailer plug and pulled out the wiring in the tongue. 548253

Trailer wiring got here just today so I can't really review this one. However, I have purchased the same unit before and it's really great. Just make sure you ground it properly and make good connections and it will work fine. Thanks again for a great product and rapid service. Robert 503080
