searched around a bit and found all sorts of bits n bobs about how this is done but don't really understand some of the technical terms used! currently have a midline that i wish to upgrade so if anyone has a definitive guide as to how this is done then id really appreciate it!
or links to an already existing how to that I've missed would also be great

Also I've bought a multifunction steering wheel as my car didn't originally have it so if it can all be tied in that'd be great!
