Most Popular 31 Feet and Longer for 2018 Nissan Titan

Replaced the wiring and lights on my 1992 boat trailer. I was able to get everything needed from etrailer. I think Optronics is of the highest quality and recommend both etrailer and Optronics product.

Works very well after re-wiring trailer lights with waterproof distribution box.

My boat trailer had a split wiring harness that had suffered over the years. I purchased this harness for the boat trailer and with attaching it to the old wire was able to pull it through the frame and connect all new lights in an afternoon.

Great product
