These items were purchased in a bulk purchase for JVC adapter cords from peripheral. They can be purchased and used with the universal iPod adapter or they can also be used as an adapter to get audio/video out of an iPhone into/ out of a JVC radio and more. Really handy connectors or they can be used to get the 5 V from a JVC uni-link plug that has the potential to change your capabilities or has the satellite output for changer/satellite, 30 pin iPod connector to audio video. No guarantees but, go to a JVC unilink breakout for how to get the pinout for the JVC plug. located in electrical room
