I picked up an older Gould PB54 differential scope probe from an electronic surplus shop for cheap in like new condition. This probe requires power +/-12V according to the probe spec sheet, however no details on the pin-out of the power connector. Some Gould scopes come equipped with the power connector on the back (see image below)

The datasheet for the probe states compatible with Gould DataSys 117 or external power unit (4101380). I searched for both of those and found nothing.
So if someone has a DataSys 117 that can measure the voltages on the power connector that would be greatly appreciated.
Any suggestions on how to determine the pin-out of the connector without damaging the probe?
