Just to expand a bit on my zeal: I have the same issue with my car. The hoses get brittle and fall off, and have been replaced with hoses with no markings.
I have some functionality but also have some ports with no hoses attached. I'd like to get the A/C and defrost working but no joy so far.
I'm not looking forward to sorting out THAT rat's nest.
