Mike, yes, the order is as listed. It may take awhile for the heat to come on. The heater control valve is vacumn. I didn't install a knob under the dash so I'm not sure what it would be. It's not a speaker control knob is it? Maybe it's a power control, turn it up for more power. Maybe it's just a knob to make you wonder what it's for.
