cle
²the right multi-function switch connector recep-
tacle
²the two ignition switch connector receptacles
²the shifter interlock solenoid connector recepta-
cle
²if the vehicle is so equipped, the Sentry Key
Immobilizer Module (SKIM) connector receptacle.
(30) Position the lower tilting steering column
shroud to the steering column multi-function switchmounting housing, then install and tighten the screw
that secures the shroud to the housing (Fig. 2).
