Polarity reversing with relays for 12vdc motor...

Hope you can help me. I am building a project in which I require a low speed dc motor (12v) to have its polarity reversed every time the power is turned off, then on again...
on (clockwise) - off-on (counterclockwise)-off-on(clockwise) etc.
I don’t want to use a switch, just replays and run the 12v from the acc from my car.

thanks in advance!
