2012 Jeep Grand Cherokee tow lights

my jeep lights all work. break,headlight,turn signal, parking lights, all work. but on my boat trailer only the marking lights don"t work. factory tow package i have on my Jeep. i tested the 4 pin plug on my Jeep. only the park lights don"t have power from jeep 4 pin plug. they have work 2 years be for this.

Fuse #14 in the under hood fuse box (TIPM) powers the tow connector tail lights, this is the same circuit that powers the side marker lights on a trailer.
