Step 1 Attach the inner rails to the sides of the controller:
a) Align an inner rail with one side of the controller so that the three keyed slots in the rail align with the three pegs on
the side of the controller (see Attaching Inner Rail to Side of Controller).
b) Set the keyed slots over the pegs, and then slide the rail toward the front to lock it in place on the pegs. The front slot
has a metal clip that locks over the front peg.
c) Install the second inner rail to the opposite side of the controller.
