I hope the other end is attached to just any nonspecific signal (ground, 3.3, 5, 12, or 24vdc). It can't hardly be from or to the amp though. The old Anilam system turned on and moved the servos. All the wires that went to or from the amps and servos have not been changed, except #2 and #11 of Amp's J1 connection now goes to the Galil.
