My Carrier furnace mod. #58RAV070-12 does not have a humidifier connection on the control board. Do I use the R and Com connections?

I have two manuals that cover that series of furnaces. They both show a HUM terminal. It's not a screw terminal. It's a 1/4" flat push-on connection. You will use the HUM terminal and the Com thermostat terminal. The HUM only supplies switched power to the humidifier. You still need a humidistat inline.
