hook [18]; then, secure its end to the left
side with adhesive tape [19].
Be sure that the secured end of the cable is
found where the hole in the left side plate
and the tip of the cable matches.

7) Lead the longer end [14] under the No. 1

mirror mount [8] and the No. 2/3 mirror
mount [9]; then, hook it on the pulley [16]
on the left front side and the pulley [17] of
the No. 2/3 mirror mount.
