1967 Pontiac Grand Prix Instrument Panel Lights Wiring Diagram - Dash Lamps

This wiring diagram illustrates the instrument panel lighting circuit for a classic vehicle (uploaded as applying to a 1967 Pontiac Grand Prix). It shows the headlamp switch with its integral rheostat at the bottom of the diagram, feeding power up through the fuse block (which is shown as viewed from the front of the car). From a battery splice (BAT SPLICE), red wires run to the fuse block and related circuits. From the rheostat splice (RHEO. SPLICE), gray wires distribute dimmable illumination power to the shift indicator lamp, rheostat lead connector, heater control lamp, radio lamp, ignition lamp, and six instrument cluster lamps. A black wire provides the instrument panel ground for the cluster lamps. Callout boxes identify the accessory feed connector, dome lamps, glove box and courtesy lamps, and the parking brake warning lamp connections at the fuse block. Wire colors identified are gray (panel illumination), red (battery feed), and black (ground). The diagram is useful for tracing dash lighting problems, identifying the rheostat splice point, and locating the fuse block connections for interior lamps.
