take all the negative (black or - wires) from the motors and hook them all togther. Those go to the neg/- part of the battery. take each wire form each motor and hook them up to each (4 swithces are needed) terminal on the switch. Then on the empty terminals next to the wired ones on the switches, buch those up and they are the positive or + on your battery. That will give you one motor per switch. That is the basic way.
