i cannot tell by looking but connectors most of the time only have one place they can go,just find the match.

the one comes from the transfer case

ive looked it over many times and so have my other buddies we cant figure it out everything is plugged in

4WD indicator light, or speed sensor.

When I have this issue I just trace it back until I find where I disconnected it from.
Are they in the same harness? if so once you find one the other will be within the distance it can reach unless the loom has been removed or wires seperated.

under hood light,ac harness,windsheild washer bottle

The one looks like the purge solenoid connector. JMO

ok the top picture goes back to the the transfer case, yes it does go to the speed sensor but where does it get plugged into in the engine bay?

windshield washer bottle is on the other side

the bottom picture is part of the wiring harness on the left side of the engine bay

well my manual only gos to 97 I cant tell

damn

Its a Haynes was in the jeep when I bought it.

i have diagrams of the wiring but it really isnt helping

find someone with the same year cherokee.... then park his jeep next to yours and open the hood.... take a roll of masking tape and run through all the harness connectors you see 1 by 1 between each vehicle, matching them up... while moving along tape previously check connectors and number them as you go.....

maybe that will help if you can manage it..and eliminate connectors leaving unplugged ones visible...
