What are these wiring harnesses for?

I'm assuming something for a higher model XJ but what would they go to? Anyone repurpose them for something useful?

Fog lights and Rear window defroster switch plugs.

The fog light switch has been repurposed to my Hella 500 driving lights relay as I do not have fog lights and fog here is rather rare. The problem with it was that it is powered by a relay that turns off the fog lights in high beam, the exact opposite of what I wanted. Hence I had to rewire it with another relay under the hood to turn on with high beam only, but the plug was useful.

I think I'll use it to add some aftermarket fog lights. Have to swing by the parts yard and see what I can find. Where do the wires from that switch end? Are they up in the bumper?

if you do not have them already you need to check the wiring harness to see if the two relays are actually in there, the Park and High Beam relays which operate on the fog lights.

FOG LAMPS
The fog lamps are controlled by the fog lamp
switch, park lamp relay and high beam relay. The fog
lamps operate only when the headlamp switch is in
the ON position, and the operator has selected lowbeam
operation. When the headlamps are in highbeam
operation, the fog lamps will not operate.
Circuit F39 from fuse 5 in the Power Distribution
Center (PDC) supplies voltage to the contact side of
the park lamp relay.
Circuit L90 supplies power to the coil side of the
park lamp relay. Circuit L35 connects to the coil side
of the relay and to circuit Z1 through the fog lamp
switch. Ground for the coil side of the relay is provided
on circuit Z1 through the fog lamp switch.
When the fog lamp switch closes, the park lamp
relay contacts close and circuit F39 passes through
the relay to power the contact side of the high beam
relay. When the headlamp high beams are OFF, the
high beam relay is not energized and voltage flows
through the normally closed contacts to circuit L39.
Circuit L39 supplies voltage to the fog lamps. Circuit
Z1 provides ground for the fog lamps.
If the high beam lamps are ON, circuit G465 energizes
the high beam relay. When the high beam relay
energizes, the contacts open and power is not supplied
to the fog lamps. Circuit Z1 provides ground for
the coil side of the high beam relay.
Circuit E2 provides voltage for the illumination
lamp in the fog lamp switch.

Look on the right side of the radiator to see if you have the relays. If you do not you will hav eto search the wiring diagrams and track down how much of it you actually have.
