1. Pull off tailgate trim board
2. pull off dust plastic
3. tie some strong string around the top of the unlock mechanism wire where it meets the pivot
4. Make it long enough to hang down to floor level
5. put back dust cover plastic and tailgate trim board with string hanging out.
just tug this string- unlocks so easy
Mind you, you should lubricate everything involved to make it super easy, maybe while you have tail gate trim board off.
