|info=This plug connects to the ITT Cannon XLR 3-Pin Female 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.
