1
Attach the sub-lead wire to the swing arm with
the tie wraps provided in this kit. Start with the
two grommets on the wire (see fi gure).
NOTE!
It is important to attach the wire in the given
order. Start with the grommets and then attach
the wire along the swing arm as described.
2
Continue attaching the sub-lead wire with tie
wraps to the swing arm as indicated on the
gure.
3
Attach the grommet (part no. 90480-23001) to
the hole in the skid tunnel wall.

tunnel.
CAUTION!
Make sure the threads on the limiter strap screws
are not facing toward the shock absorber, they
may cause damage to it. If the threads are
facing toward the shock absorber, change
their position so the threads are facing in the
opposite direction.
CAUTION!
If you need to change the position of the screws,
change position only of one screw at a time so
the limiter strap will keep holding the skid in
compressed position.
