There is not an industry standard wiring diagram for the 4-Way Round Car End, part # PK11410. You will need to use a circuit tester, part # PTW2993, to check which pins have which functions on your trailer, and then attach the corresponding wires to their respective pins on the vehicle connector.

If you are towing a vehicle behind a motor home the connections are usually as follows. The top left connection inside the vehicle end, with the cover raised, is the yellow left turn/brake connector, the top right is the green right turn/brake connector, the bottom left is the white ground wire, and the bottom right connection is the brown taillight connector.

The trailer end, part # PK11409, is a mirror image of the vehicle end with the top left being the green right turn/brake connection the top right being the yellow left turn/brake, the bottom left being the brown taillight and the bottom right being the ground.
