Location of fuse links

Good day all. So I finally got the time to remove the fuse box and locate the fuse we talked about I’ve tested it with a multi meter and yet seems to be ok however since I already bought one I wanted to replace Anyone ever changed it before be I don’t know to remove it I think I feel a small screw probably an 8mm. Any ideas will be greatly appreciated also if the fuse is good any other ideas what I can check. Is it possible my ecu I’d damaged ?

 

I finally got the time to work on the car I pulled out the fuse box got access to the fuse checked with a multi meter and it’s good I still wants to change it but I don’t know how to remove it any ideas? Also being as the fuse is good that’s still leaves me wondering what could be wrong with my car
