Replaced the transponder coax cable that turned out to be too short after I rerouted it to the panel through the center of the forward fuselage. Luckily I had some extra coax that was the perfect length. Removed all the coax cables and labeled them. Reinstalled same cables and rerouted the comm cable to the center of fuselage since I had some extra length. Added some heat shrink to the connection end of each cable for strain relief.
