Routing wire from Passenger Compartment Fuse box to Driver's side - how?

Hi, I've fitted an 'Add a circuit' piggy back fuse holder to the cigar lighter fuse (F52) in the passenger Compartment Fuse Box. That was easy enough but finding a route to the other side of the car is the opposite. Does anyone know of a relatively east way of doing this?

I would prefer a minimum of trim removal if possible - I'm always afraid things won't go back as easy as they came out!

I'm wiring in a multi lighter socket including USB charging to power my iPhone and Dashcam hence the reason for the power circuit.

Cheers,
Terboy
