Throttleup 10 Posted July 14, 2015 Mayday, Mayday, Mayday... does anyone know anything about a wiring diagram for the "power supply to the brake booster"?? A VW tech on the island says the two diagrams out there don't match my 1992 SLC! Also the giant yellow Corrado Manual in my trunk doesn't haver it as well. Any help would be MUCH appreciated!!
