Can you show schematics for how to wire the guitar?

You don't need a schematic to wire a guitar. First, find the hole that you are placing in a new string at the "Bridge" where the silver dot pick ups are located. Run the tip of the string through the hole gently pull the string until no more comes out slide the string through the hole on the neck give some slack too where you think its good enough. Wind that string up and place the string under the first coil turn, so that it has a better grip make sure it fits in the slot plastic part near the bottom of the neck groove. Bring out your guitar "tuner" and tune it up.
