powersteering high pressure switch?

ok my powersteering feed line rusted through and had to replace it. in the process i also had to replace the lower portion of the return line also. but that is here nor there, the real problem is the "powersteering high pressure switch" came apart when i tried to take it off the old feed line. what the hell does this thing do? ive been hunting junkyards cause no aftermarket shop or even the dealerships have it. it also seems that just the 2.5 is the only one that has it.
so does it really "need" this to be drivable?
and in another thread someone said something about bleeding the system. how do i do that?

1995 yj 2.5 manual on 11.50 x 31's if that means anything

You don't _need_ it. It senses when the PS pressure is high (meaning you are turning the wheel). Most of the time, nothing really special happens. But the 2.5 could possibly bog down or stall if you start cranking the wheel at low RPM (idle). The computer sees the low pressure signal at low RPM and just taps the throttle a little bit to keep from stalling.

Don't crank the wheel too much on the rocks at idle and you'll be fine. I'm not even sure that mine works and I've never stalled my engine by cranking on the PS.

Bleeding is cake. Get the front end up in the air. Open up your PS reservoir and slowly turn the wheel back and forth until no more bubbles come up. Fill the reservoir if it gets low as the air is bled out.

If you need one, the 2.5 XJ's also had them. That's where I got mine.
