It's a switch, not a relay. And it's on the tranny. The reverse light relay is on the transmission, you have wiring from the transmission to a socket style clip, that wiring section is the relay for the reverse light.
it's located to the left of the steering wheel. Romve bottom plastic bracket then the metal one to get to it, it should be on the left. If you turn the blinker on you can ;feel; the relay 'blink' to positevly id it.
If your reverse lights are not coming on when you put it in reverse there is a good chance that your neutral safety switch is shot. Check this link for information: http://98jeepbuild.blogspot.com/2009/06/neutral-safety-switch.html
i believe that the reverse light switch has something to do with the nutral safety switch because my 95 Cherokees neutral safety switch is going bad and half the time the reverse lights wont come on
It is on the same circuit as the brake lights, but if they are not working, and the bulbs are good your switch needs cleaning or adjustment.
Attempt this first since the switch costs nearly $300 bucks.
On the passengers side of the trans just behind the bell housing there is a fan shaped switch, loosen the 12mm bolt ( smaller of the two, and rotate the switch while a friend checks the lights. this problem is usually accompanied by an occasional inability to start the vehicle, but can be cured by jiggling the shifter.
While adjusting the switch make sure that the vehicle will start in park as well, remember to block the wheels while testing the back up lights, engine off, key in run but not start, shifter in reverse, move switch until lights come on.
Once you find this spot, hold it in place and have your helper check to make sure it will start. This may take several tries to get both working correctly.
If you have no luck the switch may be dirty, this happens a lot. Hold the post to the bottom large bolt still while you loosen the nut, then remove it, then remove the 12mm adjusting bolt on top, remove the wire connector and pull the switch away, remove the bolts on the switch and separate the halves, use electrical contact cleaner and maybe some q-tips to clean all the copper connections completely apply di-electric grease and reassemble, refit to the trans and readjust so all functions work, this switch controls back up and start safety.
Caution! always hold that bottom bolt while tightening the large nut, this is connected to the gear adjuster and you could damage the internals if it isn't secured while you do it.

The 1990 Jeep Cherokee electric fan relay switch is located on the firewall in the engine compartment. The fan relay switch will be on the passenger side of the firewall.
Start by removing the connections for the cruise control and brake lights, then remove the bolt that holds the switch to the brake pedal. Once the brake pedal is loose the switch is held on the brake pushrod by a bushing with nylon retaining washers. Carefully remove one washer and slide the bushing out, the switch can now be removed from the pushrod. Installation is the reverse; line up the hole on the switch with the hole on the pushrod, make sure the tabs for the cruise control and brake lights are facing properly. Reinstall the bushing and replace the other nylon washer, replace the bolt and tighten. Lastly connect the brake lights and cruise control.
It is usually located in the headlight switch. It is a automatic reset circuit breaker. When a short occurs it rapidly blinks the headlight circuit on and off so the headlights are not completely lost to allow you to pull off the road safely at night.
1990 will require an OBD1 reader
yes There was also a Laredo package for the XJ Cherokee in the 1990's.
Yes.

check the fuse for the brake lights, they have thier own. also check the brake light switch at the at the top of the brake petal
look on the brake pedal you will see a lil switch there that's the brake light switch
The brake light is controlled by a relay switch. If the relay switch is bad the brake lights will stay on. The brake light switch simply plugs in and out. Unplug the brake light switch until you can replace it.
