  3. Insert a locking tab into the forward end of the side rail and slide the tab rearward. Then reinstall the endcap on the forward end of the side rail.
  4. If your vehicle has an acces slot on the forward end of the side rail, insert the locking tab through the acces slot and slide the tab rearward.

  5. If your vehicle has the floor track covers installed, they must first be removed before continuing the installation of the side-saddle storage bins. See Floor Tracks for instructions.

  7. Prepare to insert a tapping plate into the floor track by locating the end of the plate that has the shortest distance between the end of the plate and the first stud. The distance will measure approximately 3.9 inches (100 mm).

  8. Object Number: 1338177  Size: B3
  9. Insert a tapping plate into the tailgate end of the floor track and slide it forward, making sure that the three studs on the plate are facing upward.

  10. Object Number: 1338180  Size: B3
  11. Place one of the side-saddle storage bins on the floor track so that the studs on the tapping plate line up with the holes in the bottom of the bin.

  12. Object Number: 1338185  Size: B3
  13. Slide the locking tab forward in the side rail until the hole in the middle lines up with the metal bracket on the side-saddle storage bin.

  14. Object Number: 1338187  Size: B3
  15. Insert one of the D-rings through the bracket and locking plate and loosely tighten it to the side rail.
  16. Be sure to use the D-rings supplied with the side-saddle storage system that have 0.3 inches (8 mm) studs. Using other D-rings will not work because the studs will be too long and the storage bins will not be secured properly. If you need additional D-rings and locking tabs, contact your dealer.

  17. Loosely install the three wing nuts on the studs in the bottom of the storage bin.
  18. Once the bin has been situated properly, fully tighten the three wing nuts in the bottom of the bin and the D-ring on the side rail.
  19. Install the locking lid on the storage bin.
  20. Each storage bin is delivered with two keys. If additional keys are needed, your dealer can create them using the key code imprinted on each key.

  21. Repeat the above steps to install the other storage bin.

To remove the storage bin(s), reverse the previous steps.

Be sure to load items in the cargo area according to the proper load limits. See Loading the Vehicle for more information.
