What pins do i have available on a sx3 to activate a relay? Or would going with a second port be a better idea?

There are 2 relays, that can be setup as output #1 & #2 in Mach3.
Normally these are turned on by M7 (oil mist) and M8 (coolant).
M9 or M30 turns both off.
The relays are on the Spindle Control PCB rev 1.2 & rev 1.3. There is 1 common terminal and 2 free contacts marked S1 and S2.
