5. Insert the DynoLock bracket into the inside of the tailgate from the left side with the U shaped end towards the tailgate handle. (Middle)
6. Place the predrilled 1/4’ hole in the DynoLock bracket over the threaded door lock handle stud. Replace nut but do not tighten yet.
7. Align the bracket so that the locking pin, when extended is best positioned to prevent the longest cross arm from moving up when the handle is pulled.

10. Connect the long harness to the short harness installed in the tailgate by pressing the 2 pin waterproof connectors together.
11. Run the harness under the vehicle as close to the driver’s side trim plate as possible. Use the tie wraps to secure the harness to the frame. Be sure to avoid moving or hot parts under the vehicle, i.e. shocks, springs or muffler parts.
12. Remove the driver’s side trim plate and drill a 7/16" hole in the floor under the driver’s side door trim plate and insert the enclosed grommet. Run the harness thru the grommet
13. Locate the Pink / Black (Lock) and the Red / Orange (Unlock) wires in the harness under the side plate.
