Wire Colors for 7-Way Trailer Connector on a 2007 Ford F-250/F-350


Color code for truck plug


Expert Reply:

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.
