Looks like you're nearly there.
I can find two diagrams here that have the red as the ignition live and the yellow as the permanent live:

Whether that's right or not I can't remember but it does ring a bell as for me it's counter-intuitive. You'd think red would be perm live! Lol.
I've blown fuses in head units before. Shouldn't be difficult to visually check and replace if necessary.
Looks correct to me, with green, blue, white, and grey pairs for the speakers.
