Was just what I needed to rewire my old utility trailer! Worked great!
I buy this one because of the full length ground wire. Clear instructions so I know which wires go to which side. I have put this on a couple of trailers and highly recommend it.
works good
I purchased this wiring harness to replace the original harness that came with my utility trailer. This harness is by far better quality. Easy to install and all of the lights worked first time. Would definitely recommend.
Not sure why but I started having trouble with the drivers side locks and windows Not working. Even after removing it. Could be the car I really don't know.
Great product
Perfect for what I needed no issues installing it
I picked this to rewire an old trailer. Trailer lights often fail because they are grounded to the trailer frame and the ground connections corrode. With this set it grounds from the vehicle all the way to one of the trailer lights. You then have to send a ground wire from one light to the other. I also grounded the trailer.The set comes with a vehicle harness as well, but unless you have an old vehicle with a 2 wire system you will need a 3 to 2 (not 2 to 3) converter to use the included vehicle harness and get both brake and turn signals. Easier to just buy a 3 to 2 converter with harness like the Curt 56175.
