Power steering throttle assist
I swapped a 5.0 mustang engine into my 91 f-250, when pulling the old engine I found a plastic connector unplugged down be the power steering box.
When I installed the new engine I plugged the plug back in. My engine run great , but was idling up and down. It would idle down enough to stall.
I unplugged the sensor and the idle settled down.
What is the unit on the hose called and is it really necessary?

Thanks for the info. Is there anywhere that shows what all the sensors, switches , relays,
valves etc. that are on or around these engines, what they're called and what they do?
I see a lot of threads referring to ABC valves or DEF sensors, I'm lost.

There is a power steering pressure switch? What does it do? And is it just a gasser thing, as my '90 diesel has nothing like that...

I'm not sure if it's simply a low fluid sensor or if it signals an increase in pressure when the wheel is turned so the EEC can increase rpm to compensate for the extra load. I suspect the latter but whatever the reason it's not something that is consistent on all trucks or years, I have seen some with it and some without. Yet another Ford mystery.

Must be a truck thing, as 5.0 cars don't have that... must be cause of the extra load on the front wheels when the truck is full to capacity.
