For a salt water boat trailer, I recommend using the 35 Ft 4-Way Trailer Wiring Harness item # A35W42B. This 42' harness is trimmable and has two tail light wires that split at the harness. This is beneficial because the separate wires can run down each side of the trailer to tail lights without needing a jumper wire.

You're also going to want to use the Primary Wire Heat-Shrinkable Tubing item # DW05452 to keep out the water when you're connecting to your lights.
