Radio wiring diagram please or similar

Hi had a basic search on TD5 radio wiring diagrams, but only came up with 8 replies, all very interesting but zero help! I have a 1999 TD5 with the standard Alpine fit radio cassete with cd changer under the drivers seat that does'nt work, and also what I believe is an amplifier under the passengers seat as has the Harmen Karmen (sp) speakers. I want to replace it with one out my garage. So if anyone could tell me what each wire does/plug etc I would be very greatful.

Thanks

Jeremy

Its a amplified system mate you cant just go changing wires you have 2 options
1/ rewire from the head to under the seat or to each speaker
2/ do a search for adapter kit for said stereo to standerd think autoleads and connect2 do kits for them.

Have sent you a PM
