Help identifying wire harnesses

Hey! First post here. I got my first XJ this week and I’m already trying to figure out what the previous owner did to this thing. It is a 1988 Cherokee base. I have found several connectors just floating in the engine bay not connected to anything and was hoping someone can help identify them. The first one I found was the proportioning valve sensor was disconnected and I already reconnected that one. Here are a couple more that I have found so far

First instinct is that’s a oil pressure sender plug.

Yup.

Second one looks like the one my 89 had hanging loose not connected to anything. Maybe for a hood light? I trimmed it out when I cleaned up the wiring and added an extra ground wire to the fender for the blower motor.
