69 heater A/c vacuum lines
Finally getting the controls to work
Got things plugged in. I’m not getting switch from door operation. I do have an extra all black line that I’m not sure of its placement. Is ported vacuum on a Holley enough to run the doors? Fan speed work except Hi, and cold to hot is working.

You need direct vacuum at all times. Not ported. If your fan is not working on high it could be a blown or missing fuse in the feed from alternator or it could be the high speed relay that's mounted on the firewall.
