two vacuum lines in wire loom coming from firewall
I had a small meltdown under the hood and burned these two vacuum lines on my 89 GTA TPI car now I'm trying to figure out where they go?
Do I just hook them both up to vacuum?
I think one of them is for the HVAC control, not sure about the other one?

Cool, I'll just figure out which one is for HVAC and cap the other since I deleted my cruise!

Two plastic hard lines should be only for hvac and heater control valve. Cruise control should be a rubber vacuum hose .

The one that is in #4 retainer is the cruise
The #26 goes to the HVAC
The other is the heater control valve.

Do I hook up vacuum to both the HVAC and heater control valve lines then?
