can you explain how to go about wiring my custom guitar, what kind of wires, what makes it sound different etc.
your best bet is to go to whichever company made your pickups website and pulling up a wiring diagram. How many pickups/pots/ and what type of switch are you using, and are the pickups active or passive?

EDIT: the only things that change the sound alot are different pickups and different pot values.
Out here you've gotta know where your towel is!
You might find this useful, Seymour Duncan's site has a huge collection of wiring diagrams with hundreds of configs shown.

This site has good schematics if thats what you need. I used it on the SG i pieced together
