How to plumb a hydraulic brake booster?

[Yukon Jack]

I am using a system off of a 1989 1 ton with a 454. I don't know if this will help, but here goes.

A high pressure hose goes from the powersteering gearbox #1 to #8 on the hydroboost brake master.

A low pressure hose goes from the powersteering gearbox #2 to a powersteering cooler then to the low pressure side of the power steering pump #3.

Another low pressure hose goes from the powersteering pump #5 to #7 on the hydroboost brake master.

Lastly a hose goes from #6 on the hydroboost brake master to the powersteering pump #4. I think this is a hypressure hose, but I can't tell from the attached pic or from my memory. PM me if you want me to double check as I could not find my original notes to make sure the above is correct for the #4 and #5 connections.
