I'm upgrading my panel and I'm a bit stuck on routing wires from the subpanel structure into the main spar box. The builder of the plane routed the wires down the side of the foot well (down at a straight angle to the rudder cables). They used a half inch thick piece of plastic ziptied to the wire bundle to separate them from the rudder cable. I don't particularly like this arrangement and would like to do something better, but I'm having a hard time coming up with ideas.
One idea i had was to attach a piece of cable organizer to the wall as shown on this picture: https://imgur.com/9nG72A6
. However, this would require drilling holes for either rivets or #6 screw in F713 and F719, and I'm uncertain on whether this is allowed.
Any thoughts would be appreciated. Thanks!
