Alternator fuse replacement

[wye eye man]

Hi guys, I could do with some help here.  I bought a Yaris for my daughter to learn to drive in and the Battery went flat so tried jumping it.  Unfortunately I fused the alternator fuse (the white 120A fuse)(leads wrong way around - dummkopf !!).  I pulled it thinking it would come out and it did -- of sorts !!!  Obviously not the right way.. Can you please let me know how to change the fuse.  It looks like two bolts on the side but they have a black arrow marker so I don't want to make things worse by guessing ?  Car is insured at astronomic cost for daughter to learn in so losing money all the time it is out of action -  so prompt reply would be most appreciated,  thanks in advance.

Konrad had a good thread about changing the alternator fuse on his avensis, includes some photos. Don't know whether it's identical but it's worth a look.
