What Is This Plug?

Getting ready to do my lift on Monday, so I was spraying everything down with PB Blaster. While I was doing the front shock top bolts, I noticed this plug right next to the fuse block. It wasn't plugged into anything, and I couldn't find the mating plug. Anyone have any idea what it is?

yeah the OBD II port is inside the Jeep under the dash. There are other troubleshooting ports on these Jeeps. Could be for emissions, transmission, or something else. If it makes the OP feel better I have the exact same plug not connected to anything.

All my jeeps have had it. I vote some type of diagnostic port as well.
