I'm in the same boat as Paul - my '67 originally came with underhood and luggage lamps, but both are missing. There is an orange wire in the trunk that connects to the harness in the fuel filler area, and is now just laying on the floor of the trunk. Under the hood, there is a wire attached to the voltage regulator that is routed along the left fender and ends with a connector near the wiper motor.
Both lights are missing. Does anyone have pictures of where the lights are supposed to mount and how the wires are routed?
