Hmm that might be slightly different from my own project---I'm assuming your ambulance was built as a stripped chassis and delivered to an upfitter? If so chances are good the factory equipped it with an "Auxiliary Heater Prep Pack"---this allowed the upfitter to connect the rear evaporator to the factory front A/C system. That alone shouldn't change things too much--hopefully.
I swapped out the receiver/dryer with one from my same year van that did not come with factory rear air: Motorcraft YF-37119 (Amazon @ $33.31.) Next was the condenser > evaporator line: Ford 6C2Z-19835-FC @ $88.12. Along with a new orifice tube I changed the low pressure switch mounted on the receiver/dryer as there is a different part number without auxiliary A/C.
I strongly suggest Ford OEM or Motorcraft parts as I still believe they're the best quality. This is a personal choice however. The Ford OEM $88 hose could have been purchased for much less had I had the luxury of time, found them online and through eBay for about $50. When ordering this part make sure to see an image of it first---there is an alternative part number shown in the Ford catalog for about $30 that's not correct. You'll want the exact part number I list above.
When beginning this project its best to determine what you have currently and whether it differs in any way from the factory set-up at least as far as the front A/C components. IF standard or typical compressor and hose manifold are used then the receiver/dryer and condenser > evaporator hose are different when auxiliary A/C is installed---these allow for connection to the rear or additional evaporator.
