Not sure it's possble in a M3W but I recently fitted an electric pump in mine and added an inertia switch for safety.I mounted it in the cockpit, just under the dash so I can reactive it on the move if it does trip over a bump or similar. I've also wired in a warning light, so I get a visual indicator if it's tripped.
