The routing of the cable for the Garmin GMU11 magnetometer is not mentioned in the construction manual. Since the floor of the baggage compartment isn’t installed yet it’s best to install the conduit for the GMU11 now.
I used the stringer next to the GMU11 mounting plate and drilled some 3.3 mm holes for cable ties (just like the side stringers):
The GMU11 can be reverse installed, so the connector is at the front and the cable can go directly into the conduit:
Conduit installed:
Some edge grommet was glued with Proseal to protect the conduit:
