There are 20 fuses in a box. This is very valuable as it gives you many opportunities to make mistakes during installation and further diagnostics (usually something is wrong when the fuse is blown, so the fuse will most likely blow again after installation). I made a mistake as I really need the one with the wire so we had to make our own to get it working (an idea from Youtube). We blew a few fuses before we could find the blown resistor. The resistor needs to be fixed first before we try to install another one, but I think we're going in the right direction.
