Wiring the 2019 F150 Trailer Plug
Wiring the 2019 F150 trailer plug requires some basic knowledge of electrical wiring. You will need a few tools, including a multimeter, wire strippers, and crimping pliers. Follow these steps to wire your trailer plug:
Step 1:
Start by identifying the wiring harness on your truck that will connect to the trailer plug. You can find it at the back of the truck and typically located under the bumper or near the hitch. Follow the wiring harness until you find the connector that corresponds to the trailer plug. The connector should have a cover that houses the pins.
Step 2:
Remove the cover from the connector and locate the seven pins that correspond to the functions listed in the table above. Use your multimeter to determine which pin corresponds to which function. This will allow you to identify each pin as you wire the trailer plug.
Step 3:
Cut a length of wire for each pin, and strip the insulation from one end of each wire. Crimp a connector onto each wire, and attach the connector to the corresponding pin on the trailer plug.
Step 4:
Run the other end of each wire to the appropriate location on your trailer. Strip the insulation from the end of each wire, and connect it to the appropriate electrical component on the trailer.
Step 5:
Test the system by plugging the trailer plug into the connector on your truck. Test each function with your multimeter to verify that it works properly. Ensure that you have properly grounded the trailer plug to prevent electrical malfunctions.
