Question #1: Since the truck never had a heater, I intend to get the truck running before I try to figure out if I am going to install one for my use. If I am not running a heater, is it acceptable to just plug the two places where the heater would connect? I know I could just run a hose from one to the other, but if it is not going to cause a problem, I would prefer to just plug those two openings.
Question #2: What is the small hole for in the top of the thermostat housing for?
