My a/c box has a strange looking fitting that goes through the firewall a few inches right below the firewall. It has 3 small screws that mount it on the firewall. Does anyone know what its for, looks like something might be broke on it not sure. Also where should the wire come from and run through and hook up to the blower motor? My motor has the wire in the engine compartment but no wire going to it.
You know. When I had the heater box out I looked at mine and I remember thinking "Oh that is what that is for" but I have forgotten since what the hell it was!
