ok im trying to hook up my Bazooka EL series into my Sony deck but i only have a factory Scion/Toyota harness that hooks into the Pioneer Scion deck directly. I have no idea how to wire this in, the bazooka does not have a direct RCA hookup which bites but im trying to get this done with what i have, i looked at other harnesses on the sasbazooka.com site and they have a universal one but ive been told it is just stripped wires and a direct hookup into the bazooka itself. any help with this?

oh the SOny deck model # is CDX-GT06
