How to find your fuse and the devices served by that fuse
There are 62 fuse 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

2012 F150 Fuse Diagram for Body Control Module
The battery control module (BCM) is located inside the cabin under the dash. It’s considered a smart junction box, meaning that it receives a request from a switch like a light switch or a door switch and then switches power to that device.
In other words, the switch doesn’t actually switch power to the device. The switch closure just acts as an input or a request to the BCM. By using very low-current wire between the switches and the BCM, carmakers save on wiring costs and lower the vehicle’s weight.
The BCM has 48 fuse slots, but 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 50 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
