Nope, only the diff part is Porsche. 3 speed is MB 722.0 IIRC, out of the 6.3L sedan, you can see the MB numbers on the side of the body above the pan gasket face. Locate the speedo connector in the trunk area, disconnect the plug, jack up one wheel, put a meter across the connectors, turn the wheel, you should see open circuit, closed, open, closed etc as you turn. If you do, forget the switch as a cause of problems. 99% its wiring, cruise brain, connector onto pod or speedo head itself.
