re: Looking for help with an issue with my boat trailer lights

I try to keep every connection up near the ball, to eliminate dunking connections and splices as much as practical. No connector is 100% submersible

Yes, very true.

I always ordered the same things from amazon.
-A 7 pin connector that comes with a 10' pigtail and small junction box. The junction box has screw terminals for connecting all the lights with ring connectors.
-2 conductor cable (footage varies per trailer)
-Heat shrink butt splices

I mount the junction box on the tongue, coil the the spare between it and 7 pin plug.
I then run to each light with a 2 conductor cable. This allows each light to be independently wired from others. No splicing common wires multiple times for multiple lights. No jumpers.
I make the connection at the lights with a butt splice, and then heat shrink them to seal them. This method allows you to avoid the mess with taping them.
I bring all cables into the junction box, install ring terminals, and terminate accordingly. Obviously you'll have multiple wires on some terminals, like the ground and running lights.

It is far more work to do it this way but once I'm done I know its right and will last me many years without issue.
I just hate having to splice/jump wires like the ground multiple times in the rear of the trailer or having 3 wires to one butt splice.
It only adds another fail point.
