Thanks for the write-up. I've used this a couple of times, but one thing which will make it easier is not to do this!

First, you'll need to remove the left habitrail, but before you do, you can remove the switch by pulling off the plastic cover. Just lift a little on the metal tab and pull the plastic cap off. Then you'll see what I have in the picture. If you remove the two screws, the switch will come out. Just watch out for the little metal plate on the bottom where the screws go into; that will fall free once the screws are out.

The screws/bottom plate are a pain to deal with when it comes to reassembly. If you look under the field you will see a connector, which you can unplug and it will fit through the playfield - you will be able to remove the rail easily and more importantly put it back with less drama.
The other thing I would do differently is take the u shaped plastic, supercharger cover and mountain off first/replace last - gives a bit more room for dealing with things.
But thanks to the OP for an excellent post - it gave me the confidence to take it on.
