So I’m repairing my a/c-heating system. I had an engine fire that torched an area of wiring and connections near the Map sensor. The fire completely vaporized the hard lines running from the vacuum ball line to the interior and most of the line from the heater switch doohickey. I can not for the LIFE of me find where they do into the passenger compartment. Can any of you post a diagram or photos on what to look for and how to plumb them?? Thanks!
