Vehicle speed sensing power steering
and
Engine speed sensing power steering.
Not really a S4 vs S5 thing, as some RX-7s had vehicle speed sensing steering regardless of series; however if it has power steering and is a S4 it will have vehicle speed sensing power steering or no power steering at all.
So you need to know year and model more than anything else.
For example... if you have a 88 GTU, you would have from the factory Vehicle speed sensing power steering, yet a 89 GTU would have engine speed sensing power steering.
But a 89 Turbo or 89 convertible would have vehicle speed sensing power steering.

so still not understanding what you are trying to do.
Are you putting a S4 motor into a S5 car and trying to use the vehicle speed sensing power steering pump on a engine speed sensing rack and system?

Not gonna work, unless you change the wiring, power steering pump, hoses and rack.
