Received comm and xpnder harnesses from a friend who did the termination soldering etc. Verified the correct wire was on the correct pin, then labeled with tape the names of each wire. Allegedly I'll receive a real wire label tool tomorrow so will update at that time.
Added addtional heat shrink where needed to provide some neatness at the terminatl connection point, then installed into the respective avionic trays that are part of the panel.
