I have given you part of the answer in your other thread. Here's some more:
The standard and variable assistance pumps have different part numbers but, other than the outlets, are the same.
The outlets are interchangeable between the variable assistance type and the standard type.
The difference is that the outlet from the standard pump has what is called a droop valve in it. There's a spool - a small machined part - which is loaded against fluid flow pressure by a spring. The position of that spool varies with fluid flow, regulating the power steering fluid pump pressure that goes to the steering rack.
The outlet on the variable type pump is simply a hole. That is because the low speed assistance is greater, requiring higher pressure at low pump speeds, and the final pressure is being regulated by the control valve on the rack tower.
If there's any doubt, to check what you have, with the high pressure hose removed, the pump outlet fitting can be unscrewed from the pump. It should be obvious from there.
If the replacement pump came from a VS Calais, unless the pump has previously been swapped for the standard type, it will have a variable assistance outlet. While it's possible there is a difference between VS and VP variable assistance outlets, it is not something that I am aware of. Except for a steering ratio change, the racks are the same, so it is unlikely to damage anything even if it is (different). The only possibility is the steering weight may not be the same. If they really are different, you can swap the outlet from the otherwise identical VP pump into the replacement from the VS. Are you sure that it's not just the size of the hex on the fitting that is different?
There is a difference in the pump inlets between VS and VN-VR V6 due to the change in reservoir location but, once again, the pumps are the same and the inlet can be removed from a VS pump to suit the VN-VR reservoir location.
