I have several electrical, and a few hose-type connectors under my hood that I have no idea what they are supposed to be connected too. If anything.
Vehicle in question is 86 Cherokee, 2.8, auto, 4x4.
Ive taken pictures of them, given them a reference number so you guys can make it easier to tell me what youre talking about.

This one is on the passenger side of the engine bay. Right next too those canister "thingies"

Also on passenger side of engine bay, pops out of the wiring that runs across the top of the bay.

Drivers side of engine bay, for reference you can see the bottom of the washer fluid tank in the bottom left.

Drivers side of bay, thats the coolant overflow lid in the picture.

Drivers side again, pops out of the wire loom running across the top of the bay, similar style to #2

Drivers side again, far upper right corner on the firewall, for reference thats the hood latch release cable running underneath it.
I really appreciate any info I can get on this, Ive scoured what little info I have, and cant really seem to find what this stuff is.
