The fans on a Boxster are triggered by the ECU grounding the trigger wires. You'll likely need a fan controller to do that. Simple and cheap enough.
On the later canbus Boxsters, I believe the last 1/4 of the tank is calculated by the ECU so the level just drops to zero. The low fuel light, engine temp warning light, engine temp gauge and check engine light are all on the canbus.
