W Point the tip of the clamp (sur-
plus section) to the rear side of
the vehicle. Fasten the starter
relay lead, turn signal relay lead,
main fuse lead, main fuse lead
(from the battery positive lead)
and starting circuit cut-off relay
lead with a clamp.
X Route each lead under the wire
harness.
Y Fasten the wire harness, battery
negative lead and starter motor
lead with a clamp. Point the tip of
the clamp (excessive part) to the
inside of the vehicle.P Pass the lead through inside of
the battery band.
Q Press on the tip of the clamp af-
ter passing the leads through it.
R Insert the tail / brake light lead to
the rear frame hole.
S Insert the clamp from the vehicle
front to the rear side and fasten
each lead, coupler and onion-
head to the fender rib, and then
point the tip of the clamp (exces-
sive part) to the upper side of the
vehicle.
T Hold down the clamp tips after
passing each lead.U Make sure to position the cou-
pler at the downmost position of
leads. However, the coupler
should be set in the rear frame so
that it is not caught by the seat
bottom, cover and other compo-
nents.
V Point the tip of the clamp (exces-
sive part) to the inside of the ve-
hicle. Fasten the wire harness
with a clamp.
