I have a '92 Cadillac Eldorado with Bose speakers in it. I want to replace my stock CD player with an aftermarket one, I got a wire harness and mounting kit, but I guess I need a Scosche FAI-3 adapter so I can hook up the aftermarket CD player with me Bose speakers. Does any one know where I can get one, and does any one know how I have to wire it? Thanks.
