Help!! Having hassle trying to fit radio on old alfa spider!

[JonSpiderMan]

I've got a 1976 Alfa Spider Veloce 2000, and I went to put a new Radio/CD Player in it this weekend, Unfortunately when I removed the old one it wasn't connected to anything!, I've got an old wiring diagram but it doesn't seem to have the radio connections on it and when I looked behind I just found a a mass of cables. Does anyone here know what fuse it runs off and what wires I should be looking for?

Grateful for any assistance anyone can give

the prob you might find is that someone might have messed around with the wiring before
you are probably better of running a new live with a fuse and a new earth. the speaker wires you will probably will have to trace back from the speakers
goodluck
