Worked the left side fuselage harness. This was previously just curled up on the floor; obtained some wire loom yesterday and used that to wrap the wires. Used Cobra Mounts (adhesive) to fasten the harness to the fuselage sides and up the cabin frame to the panel.
Trimmed the coax and installed a BNC connector to the RG400 for the transponder. Messed up, so had to redo with another BNC (reuined the crimp sleeve and the center pin the first time.
Measured and trimmed the comm coax on the right side of the fuselage harness; haven't installed the BNC or routed that yet.
De-conflicted wiring mess behind left side of the panel.
