Can you switch the "state" of a latching relay using a momentary 12+VDC pulse, via a NO pushbutton momentary switch?

Yeah I saw that diagram using the 4 relays, but it looks like the switch provides a pulsed/momentary ground. Now I can wire mine like that, but it would be easier (for me) to use a pulsed/momentary 12+VDC pulse. This there a way to do it using the above diagram?

O.K., I used the 4-relay set-up and it works perfectly! Thanks everyone for your help. Now, the only think I don't like about this set-up is the size of assembly itself. Can anyone recommend a smaller in size relay that can handle the loads a regular "Bosch" style relay can handle?

You could use 4 tiny relays then add one bosch style on the output as the one that carries the load.
