Got quite the task on my hands here guys! Challenging myself to re-install heat from scratch before winter and am in need of some help on where everything is gonna be connecting. Everything heating related is out of the car atm (gutted by the po) so im gonna need to know where the vacuum lines on the inner heater box go and what some of the connectors and lines go to past the firewall, below ill attach a few images of the lines that would (assumingly) go outside the firewall. theres not much good info on here about it so anyone whos got a good understanding of the hvac controls wiring harness/vacuum lines please chime in! (below are the connectors/lines in question)
