A/C hose/tubing routing map 1992 E350 Cutaway
 

I have a 1992 E350 7.3 IDI powered Cutaway Ambulance. I am converting it to an RV/Bug-out Bus. Because it was an Ambulance, it had front and rear A/C and Heater. I'm taking out the rear components because they occupy far too much space in a small RV and only work when the vehicle is in motion.
That said, all of the A/C lines are T'ed off so that a feed goes to the back. I'm about to buy A/C lines online, but I will have absolutely no idea how they were originally routed. I am hoping for anything y'all might have. Even a picture from under your hood will probably do. Saves me a trip to the next town to check out the junk yard and hope to find a 90's era van.

Thanks in advance
