i have just bought a second hand manual E90 msport leather interior to replace my manual SE cloth interior, and i'm looking for tips on retro fitting it.
the door cards and rear seats should be fairly straight forward... i'm hoping...
and i know i need to disconnect the battery negative to stop any airbag errors,
but the manual front seats have some extra electric functions like side bolsters.
does this require additional wiring?
plus i'm not sure if all msport leather seats are heated? and if they are, how difficult it is to add the controls and wiring for them?
any help will be much appreciated
