|info=There is some debate as to whether this connector is a 3 or 5 pin. Photos are not clear, but indicate this plug is a 3 pin. An ITT Cannon XLR 3-Pin Male Plug connects to this receptacle and conveys power to the right gauntlet through two plugs which then connect to two Alcoswitch/Tyco Pushbutton Switches. One switch in this power loop ignites the jet pack smoke effect, while it is believed the other turns on/off the lamp in the end of the right gauntlet.
