Thinking of putting heated seats in to 1991 850i. I'm stealing them from my 1993 ci. There dosn't appear to be any switch wires near the centre console, and I don't know if relays are involved in the seat operation.
the plugs appear to be the same in both cars. but the ci has an extra 2 wire plug on the pasenger side (secure seat warning ? ) gratefull for any help.
HAPPY NEW YEAR
