without beating about the bush, i tried to save a few quid by not buying a wiring harness and tried to do a bit of diy. i've cut 6 wires off one of the connectors (not the speakers) and would like to know if anyone out there knows which wire is which????? the vehicle we're talking about here is a FORD tranit 2002 , and i think (pretty sure) its the same BIG head unit as used in all ford cars. wire colours are--------: orange/black? green/black (50/50)? yellow/blue? green/black (75/25)? brown? green/black(50/50)?
