Its not hard to do, just need to think clearly and write down the wire colours of which does what, then make an adaptor terminal and extend the wire. One other thing, there is a location pin on the switch housing that lines up with a hole in the colum. Off the top of my head,the Mk1 hole is at 4 o clock and MK2 is at 3 o clock, so if you want the switches sitting level, you will need to drill another hole in the colum tube. I didn't bother doing it but the only thing is if you dont the light switch is quite easily knocked "on" by your knee when getting out of the car (well it is with race seats).
