rotary coupling

Hi All,

I have finally decided to change the stearing wheel control switches on my p38. At present I only have the cruise control switches fitted. I was thinking of changing the switch loam to the type complete with radio controls.

Does anyone know firstly is the rotary coupling in the stearing collum the same as a range rover already fitted with radio controls?

Is the wiring already in place behind the dash?

Hopefully it is just a matter of changing the switch loam in the stearing wheel to the type with radio controls in order to bring this function on line

Thanks

Bryan
