Auxillary Audio Input with a Parrot 3200 Bluetooth.

[CalP]

Ok, so I'm not very good at this sort of stuff.
I've put dn auxillary audio input into my SY territory, and want to hook up the Parrot 3200 Bluetooth that is in there as well. I've bought the wiring loom/switch from ASL that allows you to have 2 aux inputs hooked up, and be able to toggle them with the switch.
I've managed to get the aux audio input hooked up to it easily, but I cannot for the life if me work out how to plug the Bluetooth system in as well! There doesn't seem to be a plug that fits it at all. Is it possible this Bluetooth kit is hooked up differently and won't work with this switch? Or am I just missing something here...
