I don't think that looks right? :confused:

Terminals 3 and 4 in your post look to be the Common connections of a Double Pole Double Throw (DPDT) switch. In one position, pin 3 will be connected to pin 1, and pin 4 will be connected to pin 2. In the other position, pin 3 will connect to pin 5, and pin 4 will connect to pin 6.

A basic analogy to help you understand electric circuits is to think of electrons as water, and wires as the pipes that the water (electrons) flow through (current). Voltage can be thought of as the pressure that makes the current flow through the circuit. Switches act like valves that either shut off, or re-direct the current. Resistors restrict the flow through them. Pots are special resistors that allow some of the current flow to be tapped off at points along their length.

A circuit must provide a complete path for the current to flow through, and end up back at the same place. For your guitar, assume that the 'hot' side of the jack will have a path for current to return to the shell (or 'return' side) when the cable is plugged in.

For current to flow in the pickups, there must be a complete path from one side of a coil, through whatever circuit you connect to it, and back to the other side of the coil. Take it from there. The switches and pots add complexity to the picture, but you should always be able to trace a complete path out to the jack and back again.
