I've noticed an attached brown wire on the large plug end of the AB-TOY wiring. What's it for? I'm going to snip the exposed bare wiring part of it then cover it with a bot of elec tape (I have this thing about bare wires inside my car, especially if I don't know what they are for!). The other end of the wire goes into a jack so it has the potential to be live (or alternatively conduct power into something that doesn't want it).
