The switch to the left of the steering column is a multi-speed switch for controlling the electric fan motor. Appears to control the speed of the motor via thermal resistance.
The Motorola radio is no currently hooked up. All of the electrical and atenna wiring is present so I may at some point try putting power back to the radio.
