There are numerous threads mentioning the relay switch, but its location is never disclosed.

I see the conv. top hydraulic pump in the drivers side trunk area, but where is the relay switch? Is it located on the pump, close to the pump on the harness, or on the fuse/relay box in the trunk? Or maybe the top control unit?

Any help would be appreciated.
