Perfect Replacement Part
This was the perfect replacement for my existing and constantly shorting old version. Really can’t beat the price, instructions are basic and very easy to follow, especially for those replacing an existing harness. Coating seems durable and the length was perfect for my 5 x 10 utility trailer with some slack to spare (roughly a foot on the right light, almost 3 on the left). Works for break, stop, and L/R turn signal. Would buy again, even if it only lasted a season. I’d include photos, but I had to ship the trailer off for a new coupler as well..this dude can’t weld. 😃

Good quality
Nice protective braid sheath to protect the wires. Easy to install had just enough length for my 18 foot boat trailer.

More Protected Than My Last Marriage
For the price, this trailer wiring kit is surprisingly well made. The nylon protective sleeve and heavy-duty wiring give you confidence it'll hold up for years.The instructions, however, seem to have been written by someone who had already finished the project and forgotten how they did it. A couple of wire labels didn't match up, so double-check everything before connecting.One thing to note: the protective coating is so thorough that trimming the harness shorter isn't really practical without sacrificing some of that protection. I'll just bundle the extra wire safely near the rear lights and call it a day.Overall, excellent quality, plenty of length, and a great value. Just bring a little patience—and maybe don't trust the instructions more than your multimeter.

Nice kit for jet ski trailer
Nice complete package for rewire on a jet ski trailer. Plenty of wire. I skipped the side market lights because I didn’t want to cut into the protective cable jacket—and I’m not a very handy electrician. Very happy with the purchase.

Good harness. But bad instructions
The product is almost perfect, the instructions never mentioned the sidemarker lights. Instead of cutting the harness i just split the wire by the taillight to go to the sidemarker. The directions didn't mention the sidemarker. Also give some actual heat shrink parts.
