When the headlamp switch is placed in the PARK or ON position the dash integration module (DIM) Park Lamp Switch input is grounded.

The DIM supplies battery positive voltage (B+) to the Park LP relay coil when the headlamps or park lamps need to be on or when the ignition switch is in the ON position. Battery positive voltage (B+) is supplied at all times to the Park LP relay switch. When the park lamps are to be active the DIM grounds the Park LP relay coil. The coil is energized closing the switch contacts. Battery positive voltage (B+) is supplied to the rear fuse block RH Park LP Fuse, LH Park LP Fuse and DIMR Fuse. The RH Park LP Fuse supplies battery positive voltage (B+) to the RH park lamps. The LH Park LP Fuse supplies battery positive voltage (B+) to the LH park lamps. The RH and LH park lamps are permanently grounded so all park lamps have power and ground and then light. The DIMR Fuse supplies battery positive voltage (B+) to the DIM Park Lamp input for interior lamps dimming and the license lamps. The license lamps are permanently grounded so both license lamps have power, ground and then light.

Battery positive voltage (B+) is supplied at all times to the turn signal/hazard flasher module in the hazard switch assembly from the rear fuse block T/SIG HAZ Fuse. The turn signal/hazard flasher module is permanently grounded. Battery positive voltage (B+) is supplied with the ignition switch in the ON or START position to the turn signal switch in the instrument panel from the rear fuse block IGN 1 Fuse.

When the turn signal switch is placed in the position to indicate a LH turn battery positive voltage (B+) is input to the turn signal/hazard flasher module Left Turn Input. In response to this input the turn signal/hazard flasher module supplies battery positive voltage (B+) in an on and off flashing pattern to the LH turn lamps and the instrument panel cluster (IPC) LH Turn Input. The LH turn lamps are permanently grounded so the LH turn lamps light when they have power, ground and turn off while power is removed. The IPC will also light the LH turn indicator.

When the turn signal switch is placed in the position to indicate a RH turn battery positive voltage (B+) is input to the turn signal/hazard flasher module Right Turn Input. In response to this input the turn signal/hazard flasher module supplies battery positive voltage (B+) in an on and off flashing pattern to the RH turn lamps and the IPC RH Turn Input. The RH turn lamps are permanently grounded so the RH turn lamps light when they have power and ground and turn off while power is removed. The IPC will also light the RH turn indicator.

When the hazard switch is pressed the switch contacts close and the turn signal/hazard flasher module Hazard Input is grounded. In response to this input the turn signal/hazard flasher module supplies battery positive voltage (B+) in an on and off flashing pattern to all turn lamps. All turn lamps, the hazard flasher switch and both turn indicators then light as described above.

Battery positive voltage (B+) is supplied at all times to the stoplamp/auto trans shift lock control switch from the rear fuse block STOP LP Fuse. When the brake pedal is pressed the stoplamp/auto trans shift lock control switch contacts close and battery positive voltage (B+) is supplied to the center high mounted stop lamp (CHMSL) and the tail/stoplamps. The CHMSL, RH and LH tail/stoplamps are permanently grounded. The stoplamps light when they receive both power and ground.
