You need to use a relay. One side of the relay contacts goes to the + side of the battery and through a fuse. The other load contact goes to your manual switch, then through the lights (you need to wire them in parallel) and back to the - battery terminal. One of the coil connections on the relay goes to a switched +12v source (tail light, head light, anything that is only on with the ignition) and the other coil connection goes to the - side of the battery. That way the lights will only come on when the ignition is on AND your manual switch is on. The tail light wire should be a solid brown wire in a bundle along the left side of the bike.
