The new rotator must be
mounted in the same location
as the old one to avoid
interference with any existing
parts. The illustration shows
where to locate the fastex
grommets in the base of the
lightbar. The mirrors are
mounted as shown. All
electrical connections are
the same as the old
rotator. If you
are
replacing an
old style rotator, you
must be sure to
remove all of the adhesive
tape that the old style rotator
used for mounting.
