Since there are no data sheets for this, that I could find, I checked the wiring myself. The unit is from Bally systems, made by ACT and has P/N 105123D

Here are a couple of images of the unit.

And here’s a connection table. Keep in mind that the connections range in resistances from 30 to 100 Ohms.
