uk ford mondeo radio
 

hi all.
ive just got a new radio out of a 1990 uk ford mondeo to go in my mondeo of a later year. i did so thinking that the wiring would all be the same, but alas! i cant make heads or tails out of the new lot. its a ford factory stereo model no ford 5000 rds, with cd compatability.
does anyone know a website where i can get the wiring layout for this baby?
cheers in advance
