scooter

I am installing a AVIC-D3 and I need to figure out the speed wire and the reverse wire for an 06 honda civic ex. Where are they? What color are they? Also I need to figure out how to hook up the Bluetooth and the Sirius to the head unit. Do I go from the bluetooth out to the sirius and then the sirius out to the head unit? Help please! I'd like to get this thing started and I don't want to get half way into it and not be able to finish. Thanks for the help ahead of time.
