Never seen these small fuse box

[Alejandro Giraldo]

Do you guys happen to know what is this small fuse box for? With only one fuse ? Very cool I must say but I have no clue what where this one goes

Spade style fuses are a more modern replacement, perhaps added for radio, electric antenna, other?

I recall my Volvo 240 had a lone spade fuse in the engine bay for the electronic ignition I believe.
I can think of two reasons for deploying lone fuses, a system was added whose wiring is not part of any harness, or the system is so important that you want that fuse to stand out from the forest of other fuses that may or may not matter.

The box cover suggests it goes in the engine bay.

Exactly. Spade-style fuses aren't something BMW built into your car back in the early/mid '70's. It's as if you found a Bluetooth adapter in the car. Some previous owner installed that fuse; you'd have to trace the wiring to see what it connected to.

I had a few of these under the dash wiring up a security system, radar detector, and probably an aftermarket audio system. Definitely not original.

They are called inline fuses. They should have a pigtail coming out of the bottom to add fused power for accessory devices (such as those listed above).
