2008 Edge Fuse Diagram for the Battery Junction Box/Power Distribution Box
The power distribution box is located in the engine compartment. It contains high-current fuses that protect your vehicle’s main electrical systems from overloads
How to find your fuse and the devices served by that fuse
There are 721 fuse/relay/diode slots in the Battery Junction Box. The chart shows only 10 to speed up load time. Here’s how to find the fuse and circuit you want.
1) Change the number of entries showing (in the Show Entries Box) to 100 and scroll the list.
2) Enter the name of the component you’re searching for in the Search box.
3) Use the Next/Previous buttons at the bottom of the table

2008 Edge Smart Junction Box
The cabin fuse panel, also called the smart junction box is located on the driver’s side near the footwell by the parking brake. To remove the trim panel, slide
the release lever to the right then pull the trim panel out. To remove the fuse panel cover, press in the tabs on both sides of the cover, then pull the cover off.
To reinstall the fuse panel cover, place the top part of the cover on the fuse panel, then push the bottom part of the cover until it clicks into place. Gently pull on the cover to make sure it is secure. To reinstall the trim panel, align the tabs on the bottom of the panel with the grooves, push the panel shut and slide the release lever to the left to secure the panel.
