More wiring of stick grips. A surplus Dynon DB9 hub worked perfectly to join pilot, copilot and forward harness together. It took some creative wiring in the stick tubes as well as adding an external terminal block next to the DB9 hub. You can see on the terminal hub, the top set of 4 wires (joined by a terminal bridge, connects the Dynon autopilot disconnect wires (one from each servo) to the A/P disconnect wires from each grip. The bottom connection is one wire which combined all three Copilot ground wires (HAT switch, PTT/forward button switch, and Left/Right Buttons) to the corresponding Ground wire from the instrument panel switch. That allows/disallows copilot stick functions by either passing the ground to the firewall FOT, or not passing it . The remaining wires are from the Pilot L/R buttons and HAT switch to a local 18AWG ground on the floor rib, shown in the picture.
11 wires from each stick. Harness forward has specific functions for each stick using 9 wires.
