I just purchased this 84 and I'm going through all sort's of little repairs. I was checking on a draw so I was pulling fuses when I noticed this plug removed from the CE panel and at the panel the PO installed a jumper wire. I looked in my WM and I cant find anything about the CE panel and all the plugs at the bottom. Thanks again.

Most likely an alarm bypass.....

Exactly. Black Z plug.
Unplug it from CE panel and Jumper Z4 to Z6 to bypass the 1984 car alarm.

Look for the wiring diagrams in your WSM for 1984. There is a cryptic diagram that depicts the plug connectors A thru Z out in a perimeter view. The various wire destinations are referenced. Takes a lot of patience to figure out. If you dial-in on the one labeled Z, you will see a call-out for Z4 and Z6.
