Same as E39 pretty much. Speedo goes off of ABS Sensors, Depending on Fuel Setup if you can retain factory float you'll be fine there and tach is the same mod as the e39 with some light coding and repining a wire in the back of the cluster. EWS is unaffected because you leave the factory system in place.
