I'm getting the feeling that IF that trailer stays with me another year, I'll be doing brakes, and probably rewiring the damn thing. I think rewiring it will solve 98% of the wiring issues. I'll have to fish wires out everywhere, and I sure as hell will NOT be using stupid scotchlock connectors.
I pulled one tail light out and found almost 15 of the damn things. Looks like 3 on each wire.
