Laredo Freedom Edition without Power Outlet, and Limited model with outlet.



A rear accessory 12 volt power outlet is an option or feature on the WJ Grand Cherokee vehicles. The rear power outlet is installed in the lower right quarter trim panel in the cargo area of the vehicle, as shown in the photo above. On some, but not all WJ models that come from the factory without the outlet, a pre-wired harness is stored in the outlet area behind the carpet making the adding of the feature very easy.

The power outlet base and mount are secured by a snap-fit within the trim panel. A plastic protective cap snaps into the power outlet base when the power outlet is not being used, and hangs from the power outlet base mount by a strap while the power outlet is in use. While the outlet is very similar to a cigarette lighter base unit, it does not include the two small spring clip retainers inside the bottom of the receptacle shell that are used to secure the heating element to the insulated contact.

The power outlet base or receptacle shell is connected to ground, and an insulated contact in the bottom of the shell is connected to battery current. The power outlet receives battery voltage at all times from a fuse in the Power Distribution Center through a fuse in the Junction Block.



Outlet use with engine Off - Cautions:





Adding the power outlet to models not equipped with this option

Most WJ's that came from the factory without the power outlet have the wiring harness intact, tucked away behind the carpet in the rear quarter panel. The outlet receptacle and cap can be ordered from Jeep and easily installed.



Instructions for removing the quarter trim panel to install the outlet


CD changer housing removal
  
CD changer housing removal

1. If equipped, remove the CD changer housing and CD changer. Open the changer lid and remove the four phillips head screws that run along the top edge of the compartment hinge. Lift compartment housing straight up an inch or so until it stops and then pull straight out to remove. Disconnect the wire harness connector on the left side of the changer unit. Remove the four metal bracket nuts with a 10mm deep socket. The changer unit with its bracket attached can now be removed.

Note: it is possible to access the area where the 12v receptacle is located without removing the metal changer bracket, but the area to work in will be limited since the quarter trim can only be pulled back a short distance. The CD changer unit though must still be removed via its six side screws.

Liftgate opening upper trim piece

2. Remove the liftgate opening upper trim panel piece. The trim piece is held in place with four spring clips. Grab the edge closest to the front of the vehicle and carefully pull it down enough to release the spring clips, working from one side to the other. Tilt it down from the front and pull it back to disengage the four headliner support tabs. When reinstalling note the plastic alignment tabs and make sure they and the spring clips are properly aligned before pressing them back into place.

3. Remove the phillips screw on the right side of the lower liftgate opening trim piece. This will allow the quarter panel trim to be pulled out from under the trim piece.

4. Remove the D-pillar upper trim piece by grasping it at the top and pulling outward. It is held in place by two strong spring clips and two alignment pins.

5. Remove the two metal cargo net hooks that are attached with phillips screws.

6. The quarter trim piece can now be slid out far enough to access the work area for the power receptacle. In fact, at this point if desired the trim piece can be totalled removed by folding the seat down and releasing the snap clips on the front end. Look for the blue and red harness connector that is stored in the corner, possibly hidden under the carpet. This connector may not be present on all WJ vehicles in which case new wiring will have to be run (see info below). If the harness is found, attach the power receptacle socket into the trim panel and attach the wiring connector. The trim panels can now be reinstalled.

Note: Make sure that all of the plastic guide pins and metal spring clips are aligned properly to their slots before pressing the trim pieces back in to place.




Door trim rubber molding

7. Confirm that the door opening rubber molding is positioned over the quarter panel trim piece along the entire edge, and also along the top edge of the cargo door opening.




Adding an outlet to vehicles that do not have the factory wiring harness

(Information for the best way to run your own wiring to the back for the outlet will be provided here in the future.)
