Hi,

I attached the entire power distribution schematic below. Note that it was originally four pages in length, but I had to cut each page in half to make them readable.

I overlapped each pic so you can follow from one to the next. Also, in pic four I highlighted the switch. From there power gets distributed to many places.

Let me know if this helps or if you have questions.

Take care,

joe

See pics below.
