A/C Heat Programmer Vacuum Feed???

[Dog House]

Where exactly does the vacuum line that supplies vacuum to the A/C programmer go through the firewall? It starts at the valve that sits next to the dizzy but I can’t see where it goes? I was pulling on it to see the other end move and it came off where ever it’s hooked up. The line is only about 6” long but I can’t find where it goes back on.

It doesn't.
Vac line is in the main wiring harness and goes through the firewall as part of the elec bulkhead connector
If you are holding 6" of line then you have broken it off where it enters the harness.
Need to pull dist and open harness up to get enough line to rejoin

I guess I’ll be pulling the distributor to get access to the line to hook it up again. ad
