@PatrickTri - in case you don't know it yet - schematics are available here:
The question is - how much current is needed?
The "LED PWM" output is 24V - that's perhaps an option if the lights are not needed... and if it can handle the current?
Thats important - don't guess unless you're experienced in repairing smd components...
How does this slicing tool work?
There are some other Arduino pins available on the mainboard that can be used as an on/off trigger. But as @gr5 said - this would need some kind of amplifier board (relay / mosfet - whatever...) - maybe such a thing is already integrated in the tool?
Marlin firmware can set pin states with gcode M42. I think this alone will not fit the purpose, but who knows?

The conversion to dual extruder will be done according to the instructions.
BTW: which conversion instructions are you referring to?
@tinkergnome - are there gcodes that can set the percent for another fan like output? And what pins might be available on the UM2?
@PatrickTri - I doubt any extra pins will be able to control 24V - I think they will be 5V.
On the other hand, most UM2 printers have an extra stepper driver (you'd have to look at your board - you have to remove the 4 screws holding it in and turn it over I think to see - but there is a large, obvious, square chip roughly lined up with each connector that goes to the servos. Some newer UM2 series printers don't have a chip for the second extruder but many do.
