A. Fasten the main harness and start switch
lead by the clamp, and insert the clamp pro-
jection into the hole in the sheet metal of the
radiator. The direction of the clamp lock por-
tion does not matter. 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. Route the cylinder head breather hose out-
side the vehicle past the intake air pressure
sensor lead, and then route it above the vehi-
cle along the intake air pressure sensor lead
connector.
E. Right side of the vehicle.
F. ±10

G. Install the plug cap so it faces to the right side
of the vehicle.
H. Fasten the starter motor lead along the locat-
ing damper.
I. It does not matter if the high tension cord and
grommet do not contact the ECU.
J. Pass the wire harness between the ECU and
air filter assembly.
K. Insert the clamp into the rib so that it contacts
the rib.
