68 Heater core Barracuda pt2

In a previous thread I mentioned having bought this car wit he heater box removed. I found a replacement core and am looking into a heater box seal kit from Detroit Muscle.

The problem is, since i did not take this out, I am not certain how to hook it back up. It seems there are only two cables, which should be easy enough to figure out. I am not sure which hose gets hooked u to which part of the core. I cannot find a diagram for the wiring either.

Any help will be appreciated
