13) Connect the air control hose (A) to the waste-
gate actuator, and tighten the clamp that holds the
intake duct on the turbocharger.

Tightening torque:

3 N·m (0.3 kgf-m, 2.2 ft-lb)

14) Connect the brake booster vacuum hose.

15) Connect the PCV hose to the rocker cover.

NOTE:
Use a new clamp for the PCV hose clamp, fit the
cut out in the ST with the protrusion on the clamp as
shown in the figure, and lock the clamp.
