Electrical What is this connector for?

Hello all -
Wrapping up a project car and I have an unidentified connector. Anyone know what this goes to? It has two black wires with a white stripe.

Thanks!

I have a stock 1991 LX 5.0 AOD.
I just took a look for you and noticed the same plug and it’s not connected to anything either.
Therefore I would say don’t worry about it, seems to be like that from the factory. Lol
Someone here would know what it is though. Now I’m curious myself but at least you know it doesn’t seem to have to be connected to anything.

Windshield washer fluid test port.

It's not used. Just tuck it

Here it is on the wiring diagrams. Apply 12v and your washer will spray.

Thank you all so much!!! Have to admit, I thought it was a joke the first time I read it. Like a muffler bearing. LOL

Yeah you have no idea how much this question about this specific connector comes up.

Looks like the pig tail for the computer analysis thingy.... Although, I don't recall mine being there. I was thinking the computer hook up was on the other side.
