On my 73 the PO didn't connect the right side air/vent/heat cable, found it hanging in the wind. Where and how does the cable mount to the underside of dash?

Can someone take a quick pic of the passenger side underdash area, right side of blower motor? I have an idea where the cable clamp goes but I'm not certain.

This might help

I have the Haynes and also the FSM but neither is definitive in how the cable sheath is held in place. There are small clips that hold the sheaths for the other three cables but I can't figure out how the air/vent/heat cable is secured.

Thanks, Blue. But I need the mounting point of the cable that runs around the right side of the blower motor.

I believe it can be seen in the last 3 photos. It connects to the damper that directs fresh/recycled air.

Use the fan that is also inside that assembly for orientation.

You can follow the cable in this photo:
