CABLE ROUTING DIAGRAM
A. Fasten the wire harness, nega-
tive battery lead and starter mo-
tor lead to the upper engine
bracket (left side). Locate the
clamp end facing toward the up-
per side of the frame with the tie
end cut off on the inside of the
frame.
B. Fasten the wire harness, nega-
tive battery lead and starter mo-
tor lead to the upper engine
bracket (left side). Locate the
clamp end facing toward the up-
per side of the frame with the tie
end cut off on the inside of the
frame. Clamp the wire harness
and negative lead at the mark-
ing.
C. Pass the starter motor lead
through the hole in the relay
holder.
D. Fit the cover securely.
E. Connect the wire harness to the

enough not to crush it. Locate
the clamp end facing toward the
rear of the frame with the tie end
facing downward.
G. Fasten the (three) CDI unit leads
and taillight lead to the rear
frame. Locate the clamp end
facing toward the upper side of
the frame and cut off the tie end.
H. Connect the negative battery
lead to the battery negative ter-
minal.
I. Connect the negative battery
lead to the wire harness.
J. Fasten the wire harness to the
rear frame. Locate the clamp
end facing toward the upper side
of the frame and the tie end to-
ward the inside of the frame.
Clamp the wire harness at the
marking.
K. Pass the wire harness, starter
relay lead, starting circuit cut-off
relay lead and negative battery
lead through the hole in the relay
holder.
L. Fasten the (three) CDI unit leads
and taillight lead to the rear
frame. Locate the clamp end
facing toward the lower side of
the frame and cut off the tie end.M. Fasten the taillight lead to the
rear frame. Locate the clamp
end facing toward the upper side
of the frame and cut off the tie
end.
N. Do not allow the taillight lead to
slacken.
O. Locate the CDI unit lead be-
tween the CDI unit and rear
fender.
P. Locate the CDI unit coupler in
the clearance between the up-
per side of the CDI unit and low-
er side of the catch tank stay.
Q. Locate the CDI unit lead be-
tween the CDI unit and rear
frame.
