Audio Systems: 2000 Ford mustang, pioneer cd player, stock speakers

Question
i have a 2000 ford mustang with the stock radio and stock cd player. i am pretty sure it is a premium or mach sound system but i need to know what parts i need to hook up my stock speakers to my aftermarket Pioneer cd player. i have bought both a Scosche FD021 wire connector and a Schosche FDK106 wire connector but they don't match up with the cables in my car. can you help me?

Answer
Those mach equipped Mustangs are really a tough car to do.
Check out the photos on scosche's harness page and see if any of these would work;

they say you need to use the SLC4 level adaptor with the FDK10 harness adapter for premium or mach systems. If it not premium or Mach they say use just the FD02 harness adapter.
