Pin 7: Iout 1 for 12 V (emitter)
Pin 8: Ib 1 (****)
Pin 9: Iin 1 (collector)
Pin 10: GND

It appears as though Pin 1 is the output of an IC regulator for the 5.3 V.
Pin 3 is the Vin - 20 V typ. Pin 2 is some kind of on off control.

Pins 4-6 and 7-9 are the emitter, ****, and collector for the two
12 V outputs. These are simple Darlington transistors setup to
drive the outputs in an emitter follower configuration.
Vin typ of 30 V.

Deduced from schematic in ECG.
