Wake Plate Gauge (Black Box)

[Hayden]

After searching threads and emailing back and forth with Bennettmarine, I'm looking for help identifying what this wake plate gauge black box does? My wake plate works fine, travels up and down, full motion, no issues. My gauge has never worked since buying to boat last summer. I'm trying to figure out how to fix the gauge and in looking under the hood I found this black box from Beede wired in next to it. Searched the part number but it seems to be old as Beede may have been bought out? None of the wiring is connected as per Bennett's schematic and it looks like a previous owner may have doctored something together for some reason.

Any ideas on this thing? Anyone seen one before?
