I have a car trailer with a 2500 lb. 12V winch and I have finally gotten around to solving the problem of the small wires going to the trailer receptacle on my 2018 Expedition. I installed a second receptacle to the right of the existing one and ran a 6AWG cable from the positive battery post via a 50 amp fuse to the aux terminal and a 6awg cable from the ground terminal to the frame above the hitch. In addition I always double the cable through a pulley back to a u-bolt near the winch to halve the winch amperage.
