Solder your Neck pickups "Hot/+" to the far right lug on the right angle toggle switch.

Solder your Bridge pickups "Hot/+" to the far Left lug on the right angle toggle switch.

Combine both "Grounds/-" from the Neck and Bridge Pickups, and solder them to the Top middle lug. Just make sure these wires are only touching that lug and not the switch itself, or the previuos joints we soldered as this could ground out your whole signal.

Solder the wire(S) coming from your guitars tailpeice to the casing of any pot. On this example the tone pot was the easiest.
