Just purchased a GMOS 04 data bus interface for my 05 Silverado w/Bose and onstar. There are some wires that are not specified in the install instructions. My question is do I just leave them or do I have to connect them? There is a black wire w/yellow stripe that has a butt type connection, a red wire that comes off a black 12 pin connector and a black wire with an rca type connector. none of these is in the install instructions. Does anyone know what or where they go? Any help would be greatly appreciated. I attached a pic to show what i am talking about.
