hiya, the on off switch on mine is above the fog light on the instrument panel pinicle and not on the centre console, if u go to a land rover dealer they will be able to order it for u, look behind the blank and the wires should be there
under the drivers seat u should see a slit, if u rake aeound u will find a wire tucked under the carpet, carefuly plug the wire and a small plug should be on the end of it,
mines a former commercial 2002 , 3 door, td4 auto so i would assume it should be there
have another look , plud dont forget to buy a second hand cruise control ecu as it will be pre activated and will just be the case of plug and play, all u need then is the paddle switch for ur steering wheel, i actually bought a new steering wheel with the ive and cruise control paddles on it, think i paid around 60 quid if memory serves me right
hope u get on ok, but u must find the wire under the carpet first and in theory being the same year as mine should be there
let us know how u get on
all the best
gary
