Right. As re-drawn above you can make the black-wire Relay K2 connection to your AC Accessory common.
Additionally, I previously showed 2 red wires going to the "NO" screw-terminal of the east ITAD. This was not to imply you need to connect two wires to that screw-terminal. You can make the red-wire connection as re-drawn above...so only 1 wire goes to a any particular screw-terminal.
Those scratches are internal connections (inside the ITAD); the ITAD comes this way. I probably shouldn't have used light purple though I fattened up the scratches in above to make them more obvious. Again, you do NOT need to add these connections.
