I thought there are holes aft of both gear towers under the side panels. You can route the wires through the holes and to the top opening in the towers which is behind the panel, using the apppropriate snap bushing at the holes.
Or you can route the wires through a purchased black conduit that runs vertically along the edge where the side skin and the tower meet, down below the side panel.
Routing a bunch of wires through the tower is PIA. It helps if you have the tower mod, which I don't have.
