I had used this switchbox on my old Shadow. It mounts on top of the brake or clutch reservoir. I got it from JC whitney. I decided to put it on the Goldwing. It kind of matches the other controls.
Update: I've found that Cyclemax sells these with different finishes and switch styles.
I rewired the box with three pairs of wires. The wiring cable is from an old joystick. I think I'll use one switch for the headlight modulator. I guess the other two will be for 'future expansion'...possibly driving lights and a heated seat.
I ran the wire bundle between the switch housing and clutch lever housing in a pinch fit. This keeps the bundle from wanting to move around.
Update - Here are the functions of the switch box.
