2002 4.6L XLT 4WD Power Steering Pressure Switch (where is this thing???)

[LMHmedchem]

I was looking though a power steering part list today while putting together a list of parts for a friend.

I came across,

power steering pressure switch,

STANDARD MOTOR PRODUCTS PSS4

there were a few other models as well. I also found the part at a Ford site for my engine,

Ford 3F1Z3K215A Power Steering Pressure Switch

As usual, the kindergarten diagrams at the Ford site give no indication as to where this is installed.

I have replaced my entire power steering system including the pump, rack and pinion, reservoir, cooler, and all the hoses. I have no memory of this part when I disassembled the system. I didn't have to disconnect any wiring harnesses and there was no where for this to go that I can remember. Reading about these sensors in general, they are supposed to go on the high pressure side of the system but I have no idea where.

Does my truck actually have one of these?
Why do I not have a warning light of some kind if it's missing?
How did I miss this in taking the system apart?

Information would be appreciated.

Well that is good to know, but why does is it there at RockAuto listed under steering parts for my engine?

That I can even understand somewhat, but even worse, why does a Ford parts diagram with that part come up under my Engine?

i have no clue! but at that link it says it fits 4.0... late 9-10 mustang 4.0 there lies the difference, asyours was before that time... i suppose someone thought that they are both 4.0s so it shall interchange... it even says mine has that... yeah right!!!! my 2nd gen is about a decade before that sensor! iassume theysaid it fits a sohc, so it fits all sohcs?
