Yes. The H.L. Switch actually controls 2 seperate circuits with 2 different power feeds. Black with white tracer wire (from main harness power in splice) switches to green power wire to Floor H.L. Dimmer switch. Power from dome lamp circuit runs to H.L. Switch (pink wire pigtailed to grey clock wire at back of switch) and powers the Parking Lamps. When you turn on Parking Lamps power flows through Switch to yellow wire to Dimmer Switch. Pic shows the Dome/ Cigar Lighter circuit removed from a '70 Coronet Dash Harness. Top Right you can see the fuse tap with red and pink wires. That's where power enters this circuit.
