Remove everything from both the driver and passenger side glove box. (Some refer to the driver side glove box as the ashtray) Tilt the door of the passenger side glove box down fully by pressing the sides of the passenger side glove box, until the tab stops clear the sides of the dash opening. You may have to do this one side at a time. Lower the glove box door until the door hangs completely down. Repeat the process for the driver side glove box.

Remove the modesty panel that covers the fuse panel from beneath the steering column by pulling on the handles toward you, and set it aside.

If your truck has the Tow Command brake controller, you will find there is a tray to the left of the controller. If your truck is not equipped with the Tow Command system, you will have two small trays installed.

For trucks without Tow Command, another tray similar to the one on the left will be in its place. The upfitter switches replace the left tray.

Both trays are removed by reaching under through the driver side glove box, pressing firmly up, and then out. The Tow Command controller is removed by pressing the back of the controller firmly, which will release the retaining clips. This will expose the space where the upfitter switches are installed.

Starting at the passenger side glove box, guide the wires through to the fuse panel. Ensure that the wiring harness clears the travel of the passenger side glove box before committing to a particular path for the wiring. Make sure that the connector for the upfitter switches can be accessed through the opening you just made. Stay clear of the travel of the driver side glove box. Look for additional sound deadening insulation(white material) if it is there, tuck the wiring harness behind it. You will note that there is a pushpin connector on the wiring harness that fits into a pre-drilled hole in the dashboard frame to hold the wiring in place. Find the hole in the frame and press the pushpin in place. Using these pins makes it easy to make sure the wiring will remain in place. Once the wiring has been routed, mount the Central Junction Box mounting bracket to the dashboard frame using the bolts you purchased.

The mounting bracket bolt on the right side of the bracket is horizontal, and goes through a hole in the dashboard frame closest to the front of the dashboard and the glove box door, through the mounting bracket and the speed clip.

The mounting bracket bolt on the left side is vertical, and the mounting bracket sits on top of the existing dashboard frame, with the bolt going through the frame and into the mounting bracket and speed clip.



Feed the upfitter switch connector through the dashboard opening left by the tray you removed previously. Connect the upfitter switch wiring connector to the back of the upfitter switch. It is indexed and will only go in one way. Take the upfitter switch and connected wire and press the assembly into the dash opening on the far left side until the switch snaps in.

If you have Tow Command, press the controller in the opening on the far right side until it snaps in. If you do not have a Tow Command module, You will need a new coin tray to fill the space.

Look under the dashboard for the factory ground point on the dashboard frame, located to the right of the steering column, to the left of the driver side glove box.
Attach the ground wire connector by removing any ground bolt, adding the ground wire, making sure the tang on the connector fits into the slot, and then add the ground wire that was there previously. Replace the ground bolt.


The final part of the installation connects the upfitter switch circuits to the factory wiring harness. Remove the fuse panel out by removing the four bolts that hold it in place. You may have to lift up and then out to get the fuse panel to come free of the dashboard. To the left of center of the fuse panel assembly, you will see an eight pin male connector. It is indexed so that the connector from the central junction box wire loom can only go in one way. Plug the wiring harness connector here by pushing firmly until you hear a "click".
