Your aren’t using load shed so those should be taped up.. if your furance is working tape the two blue wires up.

Also cap the red/ black ends because if this is the zone 2 AC unit it is getting 12 VDC across the telephone cable (red/black) wires on telephone cable plug.l

Thank you for your reply. It is zone 2, I got some help from a FB group that explained the same thing to me. Thank you so much. I trimmed them back and capped all them off.
