Quite a few wires are running along the floor from the back of the plane towards the panel. So I try to make some nice bundles.
These are the magnetometer harnesses ties with lacing tape.



These are center holes through the main bulkhead below the fuel valve.



And the wire runs towards the firewall were the wires go up towards the rear of the panel.



The wires coming throug the side holes also have to be routed to the firewall. The picture shows the work partially done (the connections will be covered with heatshrink later).
