I looked up the trailer connector wiring diagram for a 2007 Ford F-250 which should be the same as a Ford F-350 and found the 7-way trailer connector to contain the following wires:

Orange = 12 Volt Power
White = Ground
Black/Green = Reverse
Blue = Brake Output
Yellow = Left Turn/Brake
Green = Right Turn/Brake
Brown = Running Lights

For a new 7-way trailer connector, I recommend using the Pollak Black Plastic, 7-Pole, RV Blade-Style Trailer Socket part # PK12-707E because all you need to do is strip the jacket off the ends of the above wires and then insert them into the back terminals on this connector.

So how is it? The little block picture doesn’t match the list of wire connections

@James Follow the list that Conner gave. The photo was a standard wiring connection diagram that typically uses different colors but I removed it for you.
