Hey guys, I'm new here on the forum and recently picked up my first Jeep.

It's a Jeep Cherokee 4.0HO 1994 and I only have 2 things left before it passes the Norwegian inspection.

One of those is a wire going from the battery into this box;




I was told by the inspectors that i need to add a fuse between the battery and this box. My question is; what is this box for and how big does the fuse need to be?

I hope someone might have an answer for me

I'm sorry if this is posted in the wrong section and for my bad english...
