A. Adjust any slack between the rear shock
absorber and the clamp of the side cover.
B. Attach the coupler cover to the coolant tem-
perature sensor coupler.
C. Pass the radiator fan motor lead to the inside
of the tension arm (the side of the vehicle).
Either the radiator fan motor lead or the har-
ness side can face the outside where they
cross each other.
D. Make sure the cable guide has contact with
the stamped location of the vehicle identifica-
tion number, and install it.
E. Insert the joint coupler into the plate and
secure it. After securing it, put the cover over
the joint coupler. It is allowed that the insert
portion of the coupler is hidden with the
cover.
F. After connecting the throttle position sensor
coupler, attach the cover.
G. Route the radiator breather hose as follows:
Route it over the boss of the upper side of the
radiator toward the rear of the vehicle
Route it over the boss on the lower side of the
radiator toward the front of the vehicle
Route it over the radiator hose toward the
front of the vehicle
H. Route the fuel hose in front of the fuel pump.
I. After connecting the fuel pump coupler,
attach the cover.
J. Route the starter motor lead inside of the rear
frame and along the rear fender.
K. Place the resistor coupler under the starter
relay.
L. Fasten the starter relay lead and motor lead
with the plastic locking tie within the range of
the cross tube width (approximately 39 mm).
Make sure that the locking portion of the plas-
tic locking tie faces to the lower side of the
vehicle and put it inside the rear frame with-
out cutting off the end.
M. Fasten the wire harness at the white tape
position using the plastic locking tie.
N. Position the lock part of the plastic locking tie
to downward of the vehicle. Cut the end of
the plastic locking tie.
O. Fasten the bracket to the tank rail (right)
using the rivet.
P. Cylinder head ridge line
Q. When installing the engine ground lead termi-
nal, it can face either way. Make sure that the
terminal does not contact the cylinder head
bolt and that it faces to the rear beyond the
cylinder ridge line.
