Please help identify this unplugged harness 1990 YJ

I was looking under the hood because my 1990 YJ when I found this part of the wiring harness that is not attached to anything. Please see the two images and help me figure out where it is suppose to be plugged in.

Thank you for your help!

JJ is correct - there should be a switch/sensor on the bottom of your power steering hose into which that plugs. It tells the PCM that you've steered hard enough at idle (or close to it) that you're risking a stall. Thus - the PCM bumps up idle to prevent it.

Correct, except the PS sensor was only used on the 2.5L engine. So that connector isn't needed. All the harnesses are generic, that's why it's there.

It looks like it hasn't been connected to anything.

It wouldn't be, the 4.2L doesn't have the sensor it would be plugged into.

According to his profile, the OP has a 4.2L. But you're right, mine didn't have PS either, until I put it in.

OoooooooooOOOooOOoOOOOOOh.....

Perhaps extend this into the cab and add a hand switch to it to increase idle speed for winching!

Ooorrr, put a bicycle shift lever in the cab to incrementally raise the idle.

You expect me to actuate a lever like a cave man, when I could be pushing a button?

If I offroaded more, it would be a bit more useful. Perhaps I should install one and then offroad more.

The PS sensor doesn't raise the idle that much. And I think it's just a short burst.

Ohio kind of sucks.

You can tell because everyone that lives here walks around looking like a tourist. They all wear "CLE" T-shirts with slogans saying how great clevleand is.
