Where do I hook up the center dash vent?
 

I am putting a late dash pad in an early car and was wondering where the center vent originally hooked up. It would be nice to have it functional.

Thanks, Matt

It originally was fed by the A/C blower. You can do like I did, and run the passengers side oulet of the fresh air blower into it. You'll need the little S piece that connects to the back of the center vent, then just run a hose from it, into the fresh air blower.
