A. Route the headlight lead (left) over the frame,
connect the headlight coupler, and then insert the
projection on the coupler into the hole in the stay
on the front fender bracket.
B. Pass the plastic band through the space between
the frame and the frame support, and then fasten
the wire harness to the frame with the band,
making sure to point the end of the band inward.
C. Route the coolant reservoir hose to the outside of
the radiator fan motor breather hose, and then
connect it to the radiator.
D. Pass the radiator fan motor breather hose through
the guide.
E. Route the throttle cable above the fuel tank shield.
F. Route the wire harness to the inside of the frame.
G. Connect the AC magneto lead, sub-wire harness,
rear brake light switch lead, and speed sensor
lead, and then fasten the leads with the plastic
band. Point the end of the plastic band inward.
H. Place the joint coupler in the area shown in the
illustration.
I. Secure the plastic band by inserting the projection
on the band into the hole in the frame, and then
fasten the wire harness at the center of its
positioning tape with the band, making sure that
the end of the band points rearward and the leads
that branch off from the wire harness do not
contact the frame.
J. Route the lean angle sensor lead to the outside of
the AC magneto lead, sub-wire harness, rear brake
light switch lead, and speed sensor lead.
K. Route the leads that branch off from the wire
harness over the crankcase breather hose, then
towards the right side of the vehicle.
L. Route the starter motor lead between the frame
and the battery box, then under the crankcase
breather hose.
M. Route the AC magneto lead, negative battery lead,
sub-wire harness, rear brake light switch lead, and
speed sensor lead between the crankcase
breather hose and the starter motor lead, and to
the rear of the leads that branch off from the wire
harness.
N. Make sure that there is not excessive slack in the
sub-wire harness in the area shown in the
illustration.
O. From the right side of the vehicle
P. Route the sub-wire harness as shown in the
illustration. The longer lead past the end of the
protective sleeve is the neutral switch lead and the
shorter lead is the reverse switch lead.
Q. Fasten the oil tank outlet hose and reverse control
cable with the clamp, making sure that the reverse
control cable does not contact the edge of the
engine stay.
R. Route the reverse control cable under the oil tank
outlet hose.
S. Forward
T. Pass the radiator fan motor breather hose and
coolant reservoir hose, then the front brake light
switch lead, main switch lead, handlebar switch
lead, clutch switch lead, and meter assembly lead
through the guide on the fuel tank shield, making
sure to route the hoses to the front of the leads. Do
not pinch or crush the radiator fan motor breather
hose or coolant reservoir hose. Route the meter
assembly lead to the left of the other leads.
U. Route the fuel hose to the outside of the wire
harness.
V. Route the wire harness above the fuel tank shield.
W. Fasten the speed sensor lead, rear brake light
switch lead, AC magneto lead, negative battery
lead, and sub-wire harness with the plastic band.
Point the end of the plastic band inward.
