Prepare the Wires
Cut the Wires
First, you need to cut the wires to the appropriate length. This will depend on the size of your cart and the distance between the power source and the motor. Cut the wires long enough so that you have some slack, but not so long that they will get in the way.
Strip the Wires
Once the wires are cut, you need to strip the ends. This will expose the bare copper wire so that you can connect it to the terminals on the motor and the power source. Use a wire stripper to remove about 1/2 inch of insulation from each end of the wire.
Connect the Wires
Now you need to connect the wires to the terminals on the motor and the power source. The positive wire from the power source should be connected to the positive terminal on the motor, and the negative wire from the power source should be connected to the negative terminal on the motor. Use wire nuts or electrical tape to secure the connections.
If you are using a battery, you will need to connect the wires from the battery to the terminals on the motor. The positive wire from the battery should be connected to the positive terminal on the motor, and the negative wire from the battery should be connected to the negative terminal on the motor.
Once the wires are connected, you can test the motor to make sure that it is working properly.
