A. Route the wire harness (to ignition coil #3) to
the left side of the cylinder head breather
hose.
B. Slide the coupler cover until the coupler is
covered and face the open side of the coupler
cover to underside of the vehicle.
C. Route the fuel tank breather hose to the left
side of the wire harness (to throttle servo
motor) and wire harness (to coolant tempera-
ture sensor). Route the fuel tank breather
hose to the right side of the wire harness (to
stator coil), wire harness (to shift sensor),
wire harness (to sidestand switch).
D. Route the rear wheel sensor lead over the
wire harness.
E. Insert the rear wheel sensor coupler into the
hole of the battery box.
F. Insert the relay unit until it touches the rib on
the battery box.
G. Insert the joint coupler into the rib of the bat-
tery box.
H. Route the rear brake light switch lead
between the wire harness and joint coupler.
(between clamp and rear brake light switch
coupler)
I. Route the wire harness (to fuel pump) on the
front side of the rear brake light switch lead.
J. Insert the clamp into the hole of the throttle
body.
K. Insert the clamp into the hole of the frame.
L. Route the body ground 3 is located above the
body grounds 1, 2, 4, and 5, and their
crimped parts of the terminals do not overlap
and face them upper side.
M. Install the crimped parts of the terminals of
body ground 1, 2, 4, and 5 to face the upper
side.
N. Fasten the rear brake light switch lead at the
gray tape with a clamp.
O. Fasten the wire harness (to rectifier/regulator
coupler) at the white tape with a clamp.
P. Point the end of the clamp rearward.
Q. Insert the clamp into the hole of the battery
box.
