 About the new airlock wires panel:
 *	An airlock wire dialog can be accessed by the normal way or by using wirecutters or a multitool on the door while the wire-panel is open. This would show the following wires, which you can either wirecut/mend or send a multitool pulse through. There are 9 wires.
