After verifying free cable movement install both cables then position the cruise control unit. Put the air cleaner adapter stud into place before tightening the bolt to 8 n.m (71 lb in) then add the outlet duct. Perform a pedal inspection by activating the ignition while the engine is off then use a diagnostic tool to monitor the tp sensor signal as you move the pedal from closed to wide open throttle (WOT) position and return to zero-percent position. Verify complete pedal freedom of movement without any binding during this testing.
