This is a tough puzzle for me nowadays.

I'd enumerate the paths of connection and judge if this is reasonable to do
with 2 relays.

Motor => Forward wiring
Motor => Backward wiring

The two wirings can't share an unswitched connection to the motor, as this
would cause a short.

So, to do this, four current paths need to be involved in switching. If any
current path is unswitched, there is a way for it to short when something
else is switched. I think!

Then, if it is two relays that guide it, is there a way to turn it off?
Couldn't you set them to opposite values? Or not?

What if you turned the relays around? So the common pin went to the motor,
and each pin was switched to positive or negative.

Then you'd switch on the direction you want it to go, and it would go that
way! When both switches were equal, it would not move.
