Finished up the service bulletin on the flap motor rod end. Already had the hole drilled and the wire run just needed to twist it and cut off. Continued to work on the center fuselage tunnel wires. Replaced a few zip ties and installed some lacing cord in between each tie down to further secure the wires. Reinstalled the flap motor wire connectors after removal of the previous ones for rerouting. Temporarily taped the wires in place on the flap motor mount. Need to add a few tie downs to secure the wires. Final installed the aileron trim servo and made the connection to the panel wire using some D sub pins and receptacles supported with heat shrink. Pinned out each wire to the ACM flap/trim connector to verify the wiring before securing the D sub pins. Placed heat shrink around each wire Dsub pin with a larger diameter piece of heat shrink to finish it off. Installation of the aileron trim servo was pretty difficult with the elevator pushrod installed. Required various tools and techniques.
