it can be powered from the Empeg serial connector (pin 4)

Has anybody actually done that? I just picked up a GPS16 the other day and was hoping to power it from the serial connector, but I don't seem to have power on that pin on either my MK2 or MK2a. I don't have a proper voltage tester to check for any current, but it won't power the GPS or a 12volt auto tester.
