This has be asked in one way or another, a LOT.
Lots of info in the archives.  More info can be found searching
variations of
things found in these archives.

Also for a reference code check in freebsd docs: led (4)

LED and GPIO pin locations can be found in manuals. 
45xx = 4501 man, and 48xx = 4801
