Installed strobe and VOR antenna RG-400 cable. Upsized holes need to 9.5mm using step drill. Used rubber grommets provided.
Used adel clamp (Aircraft Spruce - CLAMP MS21919-WDG4) on strobe wire to allow for upsizing existing hole in second rib vs drilling another hole at front of rib. Clamp will prevent wire from falling down into third rib opening where elevator swing arm moves.
Installed edge protection on top hole for strobe wire out to rudder.
