    If it only happened when the trailer is connected, then you may have a short in the trailer wiring, or the addition of the trailer lights is too much amperage load for the circuit.

    No, I disconected the 4flat and reconnected the conectors and then re-taped that and it still blows fuses. So the hitch wires are not the concern.
