How to Install Tuffy Rear Cargo Security Lockbox on your 1987-2006 Wrangler

PLEASE READ ALL INSTRUCTIONS THOROUGHLY BEFORE STARTING INSTALLATION.

ATTENTION!

• In some vehicles as a result of mounting the box on an uneven surface the lid may be offset and will not close properly after the box is bolted down. To correct this, a spacer (not included) will need to be placed under the corner of the box to compensate for the uneven mounting surface.

• It is recommended to use silicone sealant in any drilled holes to prevent any future rusting.

1. Install rubber seal on lid and rear doorframe. (SEE FIGURE 1 AND FIGURE 2)

2. For packaging reasons the cargo box is shipped without the finger pull lever installed on the rear door. The pushbutton will have to be removed and reinstalled with the finger pull lever. Before removing the pushbutton make sure it is in the unlocked position and observe the cam location so it can be remounted in the same position. Remove the pushbutton by loosening the large nut on the backside of it and maneuvering it through the hole. Slide the finger pull lever on the pushbutton. Remount the pushbutton with the cam in the proper location and tighten the large nut. (SEE FIGURE 3)

3. Skip to the mounting instructions that apply to the vehicle which the cargo box will be mounted in.

ATTENTION:

FREQUENT LUBRICATION IS NECESSARY ON THE LOCKING SYSTEM

The pushbutton lock contains an “O” ring seal to protect the interior from dust and water. If this mechanism is not lubricated regularly it will become difficult to operate and it may not return to its home position preventing the key from operating the lock. If this happens simply pull up on the pushbutton to manually bring it back to its home position. Lubricate the pushbutton with a light lubricant such as silicone spray. The pushbutton may have to be periodically disassembled and cleaned.​
