Hey, I'm looking for some info on the HVAC unit in the picture. I am assuming that this is all operated by vacuum because there are no cables. When the car was stripped under the hood a lot of the vacuum tube and canisters (???) were disconnected or removed. Is there any write ups or documentation on how these systems work? Or can anyone out there with this system snap some pics of it for me so I can try and get this going.
Thanks
Thanks
