Brake Pressure Switch Mystery???

Post by canada karl »

Hello Fivers I am replacing the good brake lines from a 03/76 530i Manual to a rusted brake line 09/76 530i Automatic. The Manual car has a brake pressure switch with the two brown wires.... but the Automatic car appears to not have the brake pressure in that location?
Not to be confused with the "Brake Pressure Regulator" that goes to the rear brakes. That is in the same location on both cars.
Was the brake pressure switch for the Automatic on a later 76 relocated or does it operate in a different way than the Manual car switch? I don't see the two brown wires for the switch on the Automatic either?
