I probably should have waited for reply for last three hours, but free time is limited, it's too late!

In for a penny in for a pound. I decided I wanted it out anyway and want to get all the unneccesary sound absorbing material out.

Now I am seeing it looks like I need to discharge AC lines to get it out so I may cut it anyway. Arrrgh... Cut carpet or not the heater core is gone now and isn't going back if I can help it.

But for the original question; can I just delete the pump and plug both ends of the coolant circuit for heater at the engine? I am pretty sure functionally it is fine, but I am wondering about causing faults in the IHKA controls.
