    I had made a prior post but need more clarity.

    I have two spst n.o. push button switches and two spdt relays (Bosch style). Can I get a laymens diagram draw so i know how to make the connections.

    I have a 12 volt battery, and a motor. I want to wire it so that when I press one button the motor spins one direction, when I press the other button the motor spins the opposite direction. THANK YOU

    You can't get much more than a Layman's drawing than inwo drew for you.
    The only thing to keep in mind is that you need to keep the button pushed for the motor to run, if you need to run unattended then you would need SPST maintained switches, using the relays shown.

    Your relays need two groups of contact, one for motor and another one for push buttons to be a self lock when the push button is released.
