It plugs straight into the E38 computer plugs and meets the chassis through Deutsch connectors, so the rest of the car only has to supply power and a few signals. Every connector and wire is new, each terminal is crimped with pneumatic heads, and every plug carries a yellow ID label for an easy install.
