Would you please explain your theory? This is so flat out wrong!
X2. There is NO connection between trailer running/turn/stop lamps and the 12v or 120v electrical systems on the trailer. There is a connection between the electric brake circuit and the trailer 12v system in the form of a 12v feed to the breakaway switch, but that should not affect running/turn/stop lamps in any way--nor should it be affected by plugging the AC cord into the pedestal. If plugging the cord into the pedestal blows fuses in the truck, there is something bad wrong.
