    Hello, my question is, how do you connect a coil relay to a motor so when a micro switch is thrown the polarity is reversed and the motor goes in to reverse?
    Do the coil pins go to the possitive and negative power supply pins, and the six relay pins connect to the motor?
    Any feedback that is positive would be greatly appreciated

    The relay needs to be DPDT. And the connections need to be wired up so as to reverse the polarity of the voltage to the motor.

    The microswitch is placed in series with the relay coil and then this is connected to your battery.

    See an example on this page.
