Replacing Carrier TSTATCCPRH01-B With Ecobee Smart Wiring Question

[GMrules]

I have Carrier 5 Ton Single Stage Dual-Fuel Heat pump with Furnace Backup and Carrier Humidifier

TSTAT went bad and Installing Eco Bee Smart Thermostat

I was reading the Installation manual and Have question about the Humidifier Connection.

My Current Wiring

R = Red
W= White
Y = Yellow
G- Green
O - Orange
Hum - Purple
C - Black

I am confused on how I need to connect, seems like I need 2 wire but not sure how I pull that off

OutDoor Sensor

Do I just Take the Purple and connect at Assy # 1
