There are a couple of fuses associated with the BSI(brake shift interlock), not related to Brake light fuse, #32(5amp).
Fuse #9(5amp), and if you have 4WD then #10(10amp), and #23(10amp)
These all power the processor in the dash, which sends power to the BSI
The BSI should have 2 wires
Blue/orange stripe is the "power"
Black/yellow stripe is the Ground
The BSI is a solenoid that locks shift lever in Park when it has no power, with key on, putting your foot on the brake should send power to the dash processor which will then send power to the BSI pulling the lock down and releasing the shift lever.
The BSI in explorers often had to be replaced, Rangers didn't seem to have that problem as much.
But check if BSI Blue/orange stripe wire has power with engine running and brake pedal depressed, if so and solenoid is not pulled in then replace BSI
