89YJ Wiring Question

I recently purchased an 89YJ and I am gradually fixing the miscellaneous broken things. While working on the horn and changing the horn relay down by the fuse panel, I noticed two plugs hanging free not connected to anything. One plug has three contacts, the other has one contact. The only two things that do not work on the Jeep are the A/C and the radio. I'm pretty sure this is not related to the radio.

It could be the rear wiper and fogs. Just guessing. Here is a link to the factory service manual. Look up the wire colors and you should be able to figure out what they go to. If you still cant post back with the wire colors on the connectors and I will look at mine:

Checked plugs today. 3-prong plug is brown, brown/white, & blue/white. The 1-prong is black.

Yes, I downloaded the manuals. Looked through it and I think you are right. Thank you for the download. I will be referencing them constantly I'm sure.

The great thing about the manuals is the wiring color is searchable because its in the standard pdf format. You need to get the wiring color abbreviations right but other then that it is easy. The colors switched so much on circuits through the years I can never remember what goes to what but the manuals will help you figure it out.
