Step One:
Get rid of that avatar.
Step Two:
Check out the Musical Instrument Makers Forum (www.mimf.com), sign up, and search the Library. When you are logged in, the Library is the first selection in the links at the bottom of the page. Don't just sign up and ask how to wind pickups, because they will only tell you to check the Library.
The Library has a WEALTH of information.
P.S.
There is no way we could fully (or even close to) explain the process of winding pickups here. You will learn much by checking out MIMF's Library.
