I just completed installing new wiring and new LED light on my Trailex trailer. It's fairly easy although time consuming.

I probably didn't need to replace the wiring but since I was going to install new lights I went ahead anyway mainly for peace of mind. I pulled a ground wire as well so that I don't have to worry about the ground failing, especially since it's an aluminum trailer. I soldered the connections in hope they are less likely fail than the other connection methods that could corrode. I insulated the soldered connections with heat shrink tubes and sometimes an extra layer of electrical tape.

You'll need 25' of wires on both sides plus some extra wires for the center rear lights. The only part that I had to disassemble on the trailer was the removal of the outside plate that holds the two aluminum beams together (the straight one where the axel is attached to and the one that goes from it to the receiver). This was needed to help feed the wires through the trailer frame.

According to a phone conversation with Trailex the nuts can be reused 6 times. I was concerned that I should be using new self-locking nuts, that's why I called.

I taped the new wires to the old one pulled them through the trailer frame as I was removing the old one. Everything was done while the boat was still on the trailer.

I choose LED lights in the hope that the bulbs won't burn out and water wouldn't cause any damage.

If you have any questions feel free to ask me.
