Matt,
WHAT A GREAT DOC!!!!
That fuse block diagram is great! It enabled me to see that in the pic I posted of the two covers, that the RH is Maserati (emblem in top left of label!) and the LH is likely a Goose, with the "frenoluce" (Brake Lights?) in teeny tiny print off the bottom of the label!!! Most people miss this, as did I for years!
Everything else lines up exactly........until you get to the bottom 2-3 positions....(BUT IT WOULD LIKELY WORK FINE!)
I think that the fuel pump position was vacated early on for our cars anyway, Perhaps the brake lights?????? Since the block has only 12 positions and 13 assignments? Someone simply added the frenoluce to the screen printing and away they went.....instant Goose part!????
So what does #11 operate?
Here is where a REAL wiring harness and working wiring would help determine what is actually where????? "Would the real fuse position #11 please come forward?!" 
I have no idea what the Mistrale 3500 is.....my youth was misguided... I liked the 3500(?) Stradas........even with Chevy 327 power....! BUT what you've shown is that indeed these blocks were sourced from "another Italian super not available" car!!
Nice work!
Steve
