wrath

Hello there! I'm looking for any information on the mechanical/ electronic elements used for Khan in "Wrath of Khan." He has a wristband with wires, a necklace, a belt buckle, and a bandolier/ chest strap. I'm a professional costumer and makeup artist, but alas, all the rest of this costume...
