A. Fasten the main harness and start switch
lead using the clamp, and insert the clamp
projection into the hole in the sheet metal of
the radiator.
The direction of the clamp lock portion does
not matter. When assembling, it is allowed to
run the leads near the radiator cap on the
inside.
B. No pinch is allowed the leads between the
tank rail and the air filter joint.
C. Insert the projection of the main harness into
the hole in the frame.
D. To sub-lead 2-pin coupler (black)
E. Right side of the vehicle.
F. ±10
G. Install the plug cap so it faces to the right side
of the vehicle.
H. Route the starter motor lead along the
damper and clamp it.
I. Face the flange of the collar toward the bolt
head and install it.
J. It does not matter if the high tension cord and
grommet do not contact the ECU.
K. Pass the sub-lead wire between the ECU and
air filter assembly.
L. Insert the clamp into the rib so that it contacts
the rib.
