A room in tg station did not have power [Fixed Pull]

Medical Bay Treatment Center, AKA the Operating Theater, was not receiving power to its APU. This was do to their being a complete lack of wiring. I have wired that APU leading out the maintenance door to the main grid.

Whether this was an oversight in making the map or you did this deliberately to give engineers something to do i am unsure. Considering by default engineers do not have access to medical it is a bit of a hassle.
