Yellow/black on the Rca 1 connector, I think. Might be RCA 2. Will I need that with the bluetooth install?

Installing next week, but prewired most of the stuff last night. Still awaiting the bluetooth and ipod units though.

the cell mute wire is for if you have a separate handsfree kit installed. A ground pulse from a handsfree kit on that wire will mute the radio until the ground is lifted. I don't beleive that wire is needed for the pioneer bluetooth adaptor, but I can't be 100% sure since I've not gotten to play with one yet.
