Trailer wiring harness

I have a 2011 Liberty Jet. I installed the hitch and wiring myself about a year and a half ago. Last week I bought a boat and when I plugged the wire from the trailer into my hitch, I popped the fuse attached to the power wire next to the battery. The 4 prong plug on the boat trailer was pretty corroded so I replaced it along with the fuse by the battery but now the trailer lights don't work right. One light constantly stays on whether the key is in the ignition or not and the other one doesn't work at all. I tried plugging in my atv trailer and its the same thing, but opposite lights. Does anyone know whats wrong here? Thanks in advance

Can we assume that the ATV trailer worked correctly for the last year?

Did you install the factory wire harness or an aftermarket harness?

Did you hide the harness is flexible plastic tubing? If not thr wires might have worn thru rubbing on the frame and then shorted out.
