I would like to find a source for a electronic gizmo which will drop voltage from 12 to 5 volts.I saw one as an aftermarket on a K16 this summer at a rally. It was connected directly to the battery and the gizmo was the size of a relay with a 4ft lead running from it to connect to a device.
Presently i have a converter connected to my SAE 2 pin plug but would like to keep this connection for a heated vest, etc.

What i would like is the gizmo to be connected to my secondary fuse panel so when i turn on the moto, power is supplied to the gizmo. TIA
