Awesome products and superb service thank you 734208
Worth it's weight in gold when it came to wiring my trailer. I bought this for a homebuilt camper project and this made wiring my lighting simple. Although, my only complaint would be the short 42" ground wire. I'm a firm believer in not using the trailer frame for grounding - I consider it a sloppy installation practice. I'd rather run the extra wires and have dedicated ground wires run to all lighting 359697
What was needed to rewire boat trailer. 640879
Great product. Nice to have two running light wires (brown pin 2)so I could feed running lights and license light without splicing wires... 158701
Tom F - 10/31/2015Website was very helpful as to finding the correct part numbers. My order processed and was shipped in great time! This is my first time dealing with this company, but not my last. I’m recommending to all of my family and friends! 609437
I recently bought a 2004 Trailstar boat trailer for a boat with a seized engine that a friend is giving me. The trailer was a great deal, but they told me the lights worked and they didn't. The connections were all corroded, none of the side lights were hooked up, and there wasn't enough slack in the existing harness to connect anything to it. Your harness was plenty long and only $15! I just wish that the ground wire was as long as the other wires. The ground wire only reached to the front part of the trailer and there's a hinge with rubber bushings halfway along the tongue. I had to ground the front part of the tongue to the part after the hinge. And then I used the ground wire in the old harness to ground the taillights. 619248
Harness was exactly what I needed and wanted. Most try to use a 4 wire system (which will do) and then split the running lite wire. 8 times out of 10 they can't get it right and end up taking it somewhere for fitting. etrailer.com had the exact item. Life is good again. quick shipping too. 615822
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! 471215
Eric - 01/29/2019Excellent 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. 146168
I 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. 497941
I am very satisfied with my experience with etrailer. The parts I received appear to be very good quality. I have not installed them yet though as I am waiting on Hurricane Michael to pass through. However the lights do seem to be very solidly built. I needed this style and etrailer was the one that had it. 572964
Perfect! 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!!!! 210017
Outstanding copper wire harness. Excellent customer service, reasonable pricing, and fast shipping with etrailer.com! Will buy from them again. 825844
The product arrived in a timely manner and meet my requirements for the job of rewiring a small enclosed trailer that was given to me. 821062
The replacement trailer wiring is working great after one year. It has not disintegrated and works excellent. It is much better than the cheap stuff I got from eBay 2 years ago that crumbled and I replaced with your superior product. Thanks for the excellent product. 820669
These guys have exactly what i need for all my utility trailers and with the really fast shipping i dont bother to try to find them in a local store..quality stuff no junk. 819792
Arrived on time, just as described, solved my issue - what else could I expect? 819302
I needed to rewire a trailer and wanted a wishbone harness so I didn't have to splice any wires for the brake lights. This harness was just what I was looking for. etrailer.com had a good price and they shipped it out right away. 817984
1 year later, lights are still doing gr eat. 811725
Exactly as described, Thank you 807708
Have not installed product yet, but product was as specified. 806542
Thanks for having the correct wire length for boat trailers And quality staff and service. 805148
This product worked great to re-wire my car hauler trailer. The factory wiring was shot and was wire nutted together from the factory with no junction box. This made the install very clean and will make future troubleshooting much easier also. 803832
1 year later things are still looking g reat! 804618
