two loose connectors under the hood

Hey, just picked up this 94 YJ project. Found two connectors not going anywhere near the alternator. Anyone know where these are supposed to connect to? Maybe a different type of alternator?
First pic shows the two wire connector sitting on top of the alternator bracket. The other connector in the third pic has just one blue wire.

All the gauges work and this Jeep doesn't have AC. Wonder if it was an optional plug for something. Looks factory though. They were just kinda flopping around when I found it. Here's one more pic I highlighted where it branches out of a bigger wiring conduit.

Well the AC compressor would sit on that bracket above the alternator. I’m pretty sure Jeep wired the, for AC even if they did not have it installed. I would also say it is for the AC.

They all came wired the same whether it had A/C or not. I'd say A/C as well based on location.

The two-prong connector with the blue center looks like a fog light plug. Check the driver side for a similar plug. A/C plug is usually round with three cavities. The one you outlined in red could be a ground cable that may have been attached near the dipstick Might wanna double check that. Either way, please post back and let us know what you find.

Without looking further I could be wrong. But is that 2-wire connector for the temp sender on the thermostat housing?
If not it may be AC clutch and therefore a nice way to turn on/off onboard air compressor....

When I installed the JeepAir kit on my YJ, I used the factory plugs for the system on the 94 harness I installed. Jbolty is right, the two prong connector goes to the A/c pressure switch, while the single prong is for the A/C compressor clutch.
