This circuit depends on the trunk latch switch being closed to provide an non-ground state to allow the top controller to activate the top pump and I believe the wing motor. If the trunk in not closed, neither the wing or the top will operate as an open trunk will interfere with the tonneau operation. This trunk latch switch is unserviceable as it is buried deep inside the trunk latch. Disconnecting it will present a non-ground state to the BCM and allow operation. I solved the same problem on my Roadster by installing a "mercury switch" on the trunk to mimic the trunk latch. Remember open circuit allows operation, ground is no go.
