Very straight forward

Was just what I needed to rewire my old utility trailer! Worked great!

Ground wire that goes all the way to the back of the trailer assures good connection!!

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 like it should

works good

Quality product

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.

Don't know why but the lock and some of my windows started not working on the drivers side

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.

Wire harness

Great product

It did the job

Perfect for what I needed no issues installing it

Full length ground wire

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.
