Just cut it off from the Porsche's system and built your own. Hardware: Arduino + automotive 12vdc relay ($20). Hand code one simple condition in your arduino backend (e.g. if >150mph then PIN#HIGH else PIN#LOW end)
The speedo analog signal can be tapped from the OBDII harness, and so its ground.
But you knew all about Arduino did you? If not it takes a day to learn on their site (ask their million-members-forum for support if you ever need lol)
