Heater-inlet Hose

I have a 1998 Rodeo. I wanted to flush the coolant, but I am unsure as to which hose is the heater-inlet to attach the tee to. Any advice as to how to locate this? Thank you in advance!

The heater hose is near the firewall on the passenger side, around the AC hoses. It's rather tight in that area so accessing that hose won't be easy. You might want to look for some other location to tap into, or if possible, use the upper/lower radiator hose (though i guess the T-fitting won't work that way). You might want to search for cooling system flush in this forum. A number of people have done it without using a flushing kit per say.
