Shift Interlock System (With Cruise Control)

The system consists of the following components:

• The shift lock relay.
• The shift lock solenoid.

When the vehicle is in PARK, the transmission range switch is closed and ignition voltage is supplied to the switch of the shift lock relay. When the brake pedal is applied, the stoplamp switch closes and battery voltage is supplied to the coil of the shift lock relay. The coil is grounded and the relay energizes. Grounding point for relay is located at right front shock tower, near horn. See WIRING DIAGRAMS  . The energized shift lock relay applies voltage to the shift lock solenoid which energizes and releases the locking tab on the floor shifter.
