Received the DB-9 connectors with nuts on one side that I ordered from Stein Air, so decided to install pins on the wires run to the bottom of the sticks and install them in these DB-9 connectors.
Assembled the connectors at the base of each stick with female pins and connectors. Installed back shells on each.
Installed pins on one of the stick grips to match the connector at the base, and installed in male DB-9 connector. Plugged the stick grip connector into the mating connector for the pilot stick.
