On my 2003 2,9crdi the last owner cut off the plug from the cruise control stalk so that he could use it for his taxi metering system. I've got a new plug but does anyone know what wires go where? I've got 6 from the stalk, blue , green, brown, black, red & yellow. On the socket I've only 5, 2x black,yellow, white & red. Anyone point me in theright direction or a wiring diagrm somewhere ? Cheers in advance.
