Help anyone!!!! Does anybody know how to wire an auto locking cap. I traded a guy for this cap so I don't have anything on it. As far as I can tell it has two wires coming from the locking mechanism. (1) Green wire (1) Yellow wire. If you give it power on the green with the yellow wire acting as the ground it will lock but if you reverse the two it will unlock. So some shape or form I need to figure out how to wire this to my truck. Thanks guys any help would be greatly appreciated.

 

That is the way the locks on the truck work also.
DC applied to the actuator pull it down, reverse the polarity and the opposite happens, the actuator pushes up ( unlock ).

In the rear driver's side door, you can tap the power lock circuit.

From what I read, pink w/black stripe + 12 V DC and pink w/ orange stripe ground is the lock direction.

This would mean:
splice green to pink w/ black stripe
splice yellow to pink w/ orange stripe

This should be the correct direction, check it when you do the install, to make sure I read the diagram correctly.

Good luck,
