SC901 question

[Thomas]

I just purchased an after market 6-CD changer for my C70 and it has a
red wire (accessory) and a yellow wire (battery) attached to the cable
that I need to connect to the matching wires that are in the wiring
harness going to the SC901 unit that came with the car. Does anyone
know what color wires that I should connect the changer wires to what
color harness wires?

Thanks
