How about posting a short "how-to" note. I would like to install a
switch like this, but don't know which wire(s) to splice into. 

Also, is it possible to remove the monitor from the main case and
extend the cable? are there any special shielding concerns?

I would appreciate hearing from anyone who has attempted these mods.
