Heater Box - Input Wanted

So turns out I was correct.... there are no more bolts holding the thing in. Just the four nuts around the blower motor, the screw between the heater hoses, and the rod in the fresh air chimney. The problem was the seal between the box and the chimney.... it was just hanging on. Thank you for those who posted input on this.

Another question... I wonder if someone can confirm what cable goes to what actuator on the box. I believe mine were hooked up incorrectly to begin with.
