So i decided to make an attempt at installing the cruise control to the A4 today, but didnt get all that far! I managed to install the Stalk, and the wiring tail for it, which went ok, however i then ran into a problem with the clutch and brake pedal switches. The switches are supposed to screw into the pedal box, one sits in the spare hole below the brake switch, and the other sits in a hole over the clutch pedal. The problem is that these holes seem to be missing some kind of insert. The existing brake light switch has a nut on it, and is held inplace nice and firmly, but the cruise switches just flop around, the holes arent threaded so theres nothing to hold the switch in place, although it looks like its machined to take something... Does anyone know if there is some kinda insert which presses into the pedal box to secure these switches? I didnt want to remove the brake light switch to see what was going on, but perhaps someone has had the brake light switch out before and knows what it looks like?
