450: 450 F Question

[Larimar450]

Wondering if anyone knows how to access/run a cable from the base of the mast to the fly bridge station? Where are the access points? Need to get a cable from the foot of the mast to the bridge station of nav equipment.

Any help or suggestions much appreciated

Follow the wire runs from the chart table to the electrical panel and then up to the flybrige.

I believe the wire runs are under the salon floor...
