through mounting plate.
2. Pull cable through hole in mounting plate (Item 7)
(Figure 12).
3. Attach switch SW2 to new mounting plate (Figures
12 and 13). Use the hardware removed from original
switch SW2 to attach switch through plate’s oblong and
small middle holes (Figure 13). Do not tighten hardware
at this time. Leave switch slightly loose for future
adjustment.

plate to frame (Figure 15). Tighten stop nuts to a torque
value of 16-18 in-lbs.
