Wrath of Khan - Khan's Accessories

[Dreamweavers]

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 is Greek to me. I bought the Star Trek Costumes book and it has some amazing detailed photos, but nothing about what they used. Any information would be appreciated. Thank you!

*I didn't take these photos, I'm just using them for reference.*

Unless I’m mistaken, there is a webpage online with a breakdown of the known parts from the costume. I’m sorry I don’t know where, but someone on the RPF will know! Good luck on the costume!
