Expert Reply:

The 2015+ Ford trucks are equipped with a so called 'smart' trailer connector that only sends power to that circuit if the proper load is applied, like a trailer being plugged in. The LED # C73NR tester won't draw enough power to activate the circuit. Additionally, the 12-volt feed needs to be set up/enabled through the on-dash info screen. The specific procedure is outlined in the Towing section of the owner's manual.
