Proportioning valve / Distribution block questions

I heard it called both.

I have two and need to confirm what I have and which one I need to use. I am running 4-wheel disc brakes.

First one is a 4-port unit I was told was for a drum/disc car. Part number on the side is F4ZC280910DA (The 8 could be a B)

The second one is a 6-port unit that supposedly came from a 84-90 Lincoln Mark VII which is a disc/disc car. Part number on the side is E5LC 2B091-CB. My net question would be where i can find a diagram to show which port goes where. Web seach has not turned up anything.

Any info would be much appreciated.

Thanks
