Introduction

In this how to guide we will be going over the procedure to relocate the STO Beast Mode fuse panel that is located under the passenger seat base to allow the RoamRig Beatbox to be installed.

The fuse panel will be relocated to under the passenger side of the dash. This requires NO wires to be cut/spliced by simply rerouting the wiring through the van.

THIS IS A SUPPLEMENTAL GUIDE FOR RELOCATING THE FUSE BOX ONLY! THE BEATBOX INSTALL IS COVERED ON SEPARATE INSTRUCTIONS.

  1. These instructions/steps assume the flooring is already removed, tool kit already removed, seat already removed, etc. This is a supplemental document in regards to our BeatBox install instructions. You can refer to the BeatBox install instructions for the full install instructions of the BeatBox including interior disassembly.

  2. Remove the fire extinguisher from the mounting bracket and set aside. Remove the small portion of the floor covering behind the seat base to expose the mounting bolts for the seat base. Remove the two rear mounting bolts and the front two mounting bolts using a 16 mm socket and wrench. Remove the seat base from the van and set aside.

  5. Pull the door seal off the body of the van along the B pillar. Gently pry the B pillar trim away from the bottom of the B pillar. You will see the wire harness for the fuse panel runs under a tab for the entry step plastic trim. Take the fuse panel wiring harness and remove it from under the tab as shown.

  7. Using a trim tool pop off the cover on the top of the A pillar. This cover is the one with "Airbag" written on it. Use a T30 Torx bit to remove this screw. With the screw removed you can pop off the upper portion of the A pillar trim. There are clips securing the A pillar trim to the body. Once the slips are free, you can pull up on the A pillar trim to remove from the dash area. You may need to used some force to pop the clips free. There are two of them that secure the A pillar trim.

    • If you have a headliner shelf installed, you will need to remove it. Follow the manufacturer instructions on the removal and reinstallation of the headliner shelf.

  11. ENSURE THE BATTERY IS DISCONNECTED BEFORE REMOVING THE AIRBAG!!!!! The side curtain airbag is held in place by two metal clips. These clips have a tab that locates them onto the mounting points for the headliner shelf. Use a flathead screwdriver and insert the tip into the mounting clip on the left side. Ensure you are not in the threads of the mounting point. You need to grab JUST the outer airbag mounting clip with the blade of the screwdriver.

    • Use a flathead screwdriver and insert the tip into the mounting clip on the left side. Ensure you are not in the threads of the mounting point. You need to grab JUST the outer airbag mounting clip with the blade of the screwdriver.

    • Lever the screwdriver outwards while putting upward pressure to "unhook" the tab from the van. This may take some practice, so be patient. Care needs to be taken to not damage the headliner.

    • We have found once you remove the left side clip, you can slide the airbag to the left to disengage the right side clip.

    • Sometimes putting upwards pressure on the side curtain airbag with your palm on your free hand can aide in the process.

    • The airbag can just hang when it is removed.

  12. Remove the trim piece above the kick panel by just pulling straight out. Remove the kick panel by removing the two panel clips and the one T20 Torx screw. To remove the kick panel after the fasteners are removed, you will need to separate the kick panel from the step cover by prying up on the step cover to have enough space to remove the kick panel tab.

  13. Ensure the harness is routed in front of the airbag at the B pillar, this will allow the harness to be placed above the airbag as it is routed to the front. Continue routing the harness forward going above the airbag and the mounting points for the airbag as shown. It is very important the harness is routed ABOVE the airbag so the harness does not effect airbag deployment.

  16. Place the fuse panel harness behind the dash as shown. You will ened to get the harness behind the dash so the cover trim will fit. The area where the harness needs to go is marked in red. This can be tricky, but you just need to get the wire behind the panel.

    • Sometimes using a trim tool to help push the wires in helps. You can also remove the screw to gain more room to get the harness behind the dash panel.

    • If the harness is not behind the dash panel, the trim panel will NOT fit.

  17. Once you have the wire for the fuse panel successfully routed behind the kick panel, you can place the fuse panel as shown. Upside down next to the other modules in the kick panel. Ensure the fuse panel is high enough to allow the kick panel to be reinstalled. Use zip ties to secure the fuse panel to the OEM wire harness in the kick panel area. Ensure the fuse panel is secured throughly.

    • Reinstall the visor shelf back into place using the T30 Torx screws previously removed.

  23. Installing the visor can be tricky. There is a hook on the visor that needs to hook into the METAL of the headliner area, and not just the plastic on the visor shelf. If the visor is not properly hooked into place, you will not be able to install the screw that secures it.

    • The next step shows a video of the process.

    • Hook the visor into the slot, then roll the visor into position. Then push it forward to get it to seat properly into the visor shelf. Once it is hooked in seated, the screw can be installed.

  24. Reinstall the door seal around the door frame by firmly pushing it into position around the door frame.
    • Reinstall the door seal around the door frame by firmly pushing it into position around the door frame.

    • Ensure the seal is even installed along the door frame and is properly seated.

  25. Reinstall the seat base using the 16mm bolts previously removed. Align the seat base in the same position it was in previously. by lining up the paint finishes. (you shouldn't see primer under the seat base mounting flanges)
    • Reinstall the seat base using the 16mm bolts previously removed. Align the seat base in the same position it was in previously. by lining up the paint finishes. (you shouldn't see primer under the seat base mounting flanges)

    • Start all 4 bolts before tightening any of the bolts down. Take care as to not lean or put pressure on the seat base as you are securing it. This can cause the seat base to tweak to one side, which will make installing the seat to the base difficult because the seat base will not be "square"

    • You can now proceed with the rest of the BeatBox install.
