-Finished up by crimping a loose ground from the shielding that I missed yesterday. Then it was time to put the harness in the airplane - not a trival item. There is a mess of wires going fore and aft. Turned out pretty good. With the D-sub plugged into the intercom it has just enough room above the infinity stick grip terminal. In hindsight I would have positioned the intercom more forward. There is alot of stuff going on in the right hand console and I haven't finished up all of the wires that go to c/bs (10 more).
Intercom harness installed.
Here are the wires loosely routed through the structure for the headset plugs
