A better way to do this is to use diodes to rectify the incoming voltage of either positive or negative polarity and send it to either one relay coil or the other of a relay as needed. You would still have one wire but always have a voltage to the relay when it is sent. The method you describe would result in the relay failing to operate properly.-Ken
