Lock
When the switch is moved to the LOCK position, voltage is supplied to the P33 circuit, and then to the door lock motors. The ground path is provided on the P34 circuit back to the right
door switch. The ground is passed through the switch internal bus bar to the P36 circuit. The P36 circuit goes to the left door switch and through to the Z8 circuit. The Z8 circuit then goes to the grounding point at the left center instrument panel support.
