Alright, so does the positive just go to any open VFAN pin?

Using Heater 3 as Fan 3
Hello I'm rather new here. I had a bad fan in a 2 fan setup for my part cooling fan and I've just now figured out that it must have fused the mosfets for it. And unfortunately when it stopped working on Fan 0 I moved it to fan 2 and the same thing happened.
I'd discovered that I can use Heather 3 as a fan. And as far as I can tell I have it configured correctly. But I'm not sure which wires should go to which pin.
I believe the negative wire should go to pin 8 on the expansion slot, but I'm not sure where to hook the positive wire up. I've connected it to the various "VFAN" pins and it runs constantly.
My GCode is:
M307 H3 A-1 C-1 D-1 ; disable heater 3 to make it available M106 P3 A3 S0 I1 H-1 F500 ; fan 3 uses logical pin 3, which is heater 3
As far as I can tell that should be the correct gcode. So the only thing I can think of is the wires not in the right place.
Any help would be greatly appreciated. I can't afford a new board right now and I don't know anyone that could replace the mosfets.
