Steve,
When I initially read this ...
Remove the climate control vacuum lines block. This is a single piece of flexible plastic, to which all vacuum hoses are molded. The hoses likely will be of different colors. To remove this connector from the back of the CCU, gently pry it off.
...it made me think of a piece of rectangular plastic, that the hoses were attached to, that needed to be pried off ..of what ...that is what I was looking for and could not find.
Then I flipped the CCU over to where I got a better look at the colored hoses. I was then able to see the clear strip of plastic holding the hoses together. Initially I had thought if I tried to pry the hoses off they would be loose, and I had sure better label them, so as to get them back in the same order.

Maybe if it said something like...
Remove the climate control vacuum lines at the back of the CCU. There is a single clear piece of flexible plastic across the hoses, to which all vacuum hoses are attached to keep them in order. The hoses likely will be of different colors. To remove this group of hoses from the back of the CCU, gently pry bit by bit at each hose connection until loose.

Thanks,
Andy Smith
