Hi Olivier. Below is picture of fuse box on my 2018 Roadster.

The power steering fuses are the large 40 amp orange one to right of picture adjacent to main 80 amp power distribution fuse. There is also a a power steering control fuse 18, 10 amp, in the engine fuse group lower left. This fuse is adjacent to unused fuse positions 19 and 20 for position reference.
Reading about this issue it appears that PAS should have been fitted from the introduction of 3.7 Roadster in February 2012. In fact it didn't appear until March 2013.
Regarding handbrake position, the parts book and diagrams suggests no distinction for l/h or r/h drive cars. The handbrake was always, intended at least, to be on the left.
