Jeep Cherokee XJ Custom Spoiler/Decklid & Spoilerlight | 1997-2001

Unscrew and remove your original third brake light and temporarily secure the wires with electrical tape for Step 7.  Place the spoiler on your XJ with the pilot strips sticking out of the spoiler so they lay flat on the roof of the vehicle.  The pilot strips are used to determine where to drill the holes to mount your spoiler.  Take your time to position the spoiler on the tailgate so it sits correctly/properly on the tailgate.  Once you have determined the correct position of the spoiler on the tailgate, you will want to use your painters tape to tape the pilot strips down to the top of your XJ.  Once you have taped them all down, you will want to remove the spoiler from the vehicle while leaving the pilot strips taped down to the top of the vehicles tailgate.

In this step you will be drilling through the pilot strips from the outside top of your tailgate into the inside of your tailgate in order to fasten the spoiler to your XJ with screws.  The spoiler is reverse fastened with screws from the inside of your vehicle.  After step 2, you should be left with the pilot strips taped to the top of your XJ.  You will want to drill through the holes of the screw top area of the pilot strips down through the tailgate into the vehicle.  The pilot hole strips should align with the holes on the spoiler for reverse threading and securing the spoiler to your XJ.

Use the screws provided in your installation packet to screw/fasten your spoiler to the top of your XJ.  Do not over tighten.   After this step you should be finished with the most important parts of the installation.  The spoiler should be installed and fitted properly and ready to paint.

Remove the spoiler from your XJ by unscrewing the spoiler and preparing it to be painted.  We highly recommend you have your spoiler professionally painted.  We recommend using MAACO Paint Centers as they are highly affordable and do a very good job matching your vehicles original paint.

Please be careful not to handle and install your spoiler until it has sufficiently dried and may be handled.  Find a soft secure place to lay the spoiler to install the 3m tape.  We recommend your bed, couch, or use a moving blanket so as not to scratch your spoiler.  Place the spoiler upside down.  Find the 3M tape (Included) in your installation packet and line the entire perimeter of the spoiler with the 3M tape.  You will want to create a seal around the spoiler so no water and condensation can seep underneath the spoiler.

Locate the wiring on your new spoilerlight installed in your spoiler.  There is a red wire (positive) and a black wire (negative).  You will need to splice the red wire of the spoilerlight to the original red wire for the third brake light located in the hole of the tailgate.  You will want to repeat this step for the black wire.  We recommend using black electrical tape to cover any exposed wire to ensure the wiring does not come in contact with any metal surfaces which can caused electrical shorting.  After you have wired up the light, please turn on the ignition to test the light by stepping on the brake of your XJ.  It should light up.  If it does not light up, check your fuse box to make sure the fuse isn’t burnt out.

Remove backing of 3M tape on the back of the spoiler.  Get ready to place the spoiler on your XJ.  Feed remaining wiring from spoilerlight into hole of tailgate and place the spoiler in the proper position on the vehicle.   Lift tailgate and screw spoiler to vehicle.  Installation Complete.
