Not that simple...
It depends on how you plan to control the humidity. Generally, simply running the a/c does a very good job of de-humidifying the house, because cold air is capable of holding less moisture. The cooling fins are continuously causing water to condensate out of the air.
However, if you override the thermostat with the humidistat your cooling will run until the desired relative humidity is reached. Here's the kicker, with a reheating coil, the lower the temp goes, the higher the RH goes... remember, reltive humidity is humidity relative to saturation point. and cooler air has a lower saturation point. The reheating coil heats the air after it's been de-humidified by the cooling coils, dropping RH... So, having said all that... do you have a reheating coil?
Generally, reheating coils are used in industril/commercial applications where high RH is a concern (like food production facilities for example), but not so common in residential applications.
Also, your HVAC wiring is not standardized (industry wide) even though there is usually some 'pattern' and 'similarity' across installs. so without referencing a DMM & a wiring diagram, you can't be sure the colors line up, or match properly... or even matter at all!
I'm not sure I'd (personally) open this can of worms unless you needed a VERY high degree of humidity control...
