Solder wires to one of the leads on both motors. Then solder both of those to one end of the battery. Next Solder a short wire to one of one of the motors leads. Attach a longer wire to the other motors lead. Solder the potentiometer to the short wire, solder a wire to that then connect that with the longer wire. Attach that to the switch then to the other end of the battery. The picture will help a lot.

Before anyone rant... I realize that anyone with any knowledge about basic electronics knows that electricity always takes the path of least resistance so wiring in a parallel isn't the best choice if I want to use a potentiometer. I wanted to only have to use one battery so I did. The potentiometer, if you're careful with it will change the speed of the one motor without stopping completely. If you want to wire in a series, it doesn't take too much knowledge to do that, so you can if you like.

Sorry for all the words.

you should post a better layed out picture, maybe an obvious schematic or something to show a better view of the circuit
