HAC system diagram

[overkill131313]

for the life of me I can not figure where the forth line is or went......there is one spot on the very bottom of the HAC unit but I can not find a hose to fit it.....anyone got a pic or diagram of the hoses on this unit? 97 Summit 670 but I think they are all the same.

I got rid of all my manuals, but if I remember correctly. It was one to the air box, 2 to the carbs, and one was a vent that just dangled down.
