I soldered the wires to the auto pilot switch, which will select the auto pilot source to be either the EFIS or the GTN-650.
I labeled the PTT wires for the low fuel warning and the annuciator board.
I laced up a few more wire bundles.
I removed the annunciator board in preparation of adding the wires for the CO annuniciation and for final modification of the board to enable each port for either a high or low input.
