2008 e93 hardtop problem

The movement direction of the hardtop and rear module are determined by corresponding
valve positions and by reversing the direction of rotation of the pump. The hydraulic
pump in the hydraulic unit is driven by an electric motor that operates in two directions of
rotation. Both rotation directions are implemented with a relay switch.
The pump motor and the five hydraulic valves are activated by the CTM. The power consumption
of the electric motor is about 40A (safeguarded by a 50A fuse). This is from the E93 retractable hardtop publication.

Question. Can anyone tell me where this fuse is located?

Did anybody ever figure out where this fuse is?

I'm having an issue with my motor not turning on anymore because I accidentally shorted some combinations of pins 87, 87a and 30 on the pump relays while trying to fix those salmon relays. I have tested my motor with an external power source and it works, but when powered from the relays it does not turn anymore.
