What is this black capsule near the driver's side fuse box?

I could use your help identifying this item pictured below in this 2002 4Runner. It is near the driver's side area fuse box to the left of the brake pedal. Please let me know if you can identify it. Thank you.

 

Suicide pill, in case you have in laws in town

 

Extra storage

 

Fuse holder for something aftermarket?

 

Sure looks like an after market, in-line fuse holder to me. I don't have one in my 99, I'm almost certain. I've been down there adjusting the clutch pedal, and I saw nothing even close to that.

If you figger it out, let us know. I'm curious, now

does it have a wire at both ends ? it certainly looks like the old style inline fuse holder

 

Yes, it has a wire at both ends.

 

Ok then it is a fuse holder follow the wires and see where they go do not put a fuse in it until you know what is at both ends
