Is the heater stepper motor meant to do this?

Further to my previous thread on fitting the stepper motor, I think I’ve figured out the wiring for the motor I have obtained. Last piece of the puzzle is to confirm that the stepper motor is meant to “bottom out” on ignition to find its reference point? I know it runs for 10 seconds on ignition but wanted to check the bottoming out is correct as a way to find its starting point.

If anyone can confirm that, I can put my car back together!

there shouldn't be a need to put a microswitch in, yes it's a crude design but having spoken to a couple of TVR specialists, they confirmed that when it bottoms out, the motor doesn't or shouldn't damage itself and uses that as it's reference point, so I'm happy enough with that.

yes I got it sorted in the end.

My next problem is that I can't get the silicone pipe back on under the dash, so going to have to take the dash top off.

Firstly, I can't even find the bolts that hold it on with my hands
Secondly, the flaps above the silicone pipes in the dash top itself (non return flaps I guess) are clanking around when the air is on. Is there an easy fix for this if I ever get the dash off?!
