Wiring Harness for 16 Foot Load Rite Boat Trailer

Question:

I am trying to find out what wiring kit would work for my 1990s Loadrite trailer for my 16 foot boat. I guess it is a 4 way with running lights including some on the frame blinkers an brakes. Tom

It sounds as if you're needing a wiring harness to set up your lights on a typical boat trailer.

Boat trailers usually use what's called a wishbone harness, like part # A20WB. A wishbone harness uses two separate leads for the running lamp circuit, one runs down the driver's side with the left turn/brake lamp circuit, the other runs down the passenger side with the right turn/brake lamp circuit. This makes for an easier installation, as you won't need to run run the wire down one side, then run a jumper over to the taillight on the other side.

I've seen folks use zip ties to hold the wiring harness in place on the trailer frame, and that works just fine but using clips like part # CE16867A would make for a neater, more professional looking installation. If you click the provided link, you can see a video showing a typical install.
