Your connections look correct.

I don't think the permanent +12 uses a 15A fuse, but I wouldn't upgrade from what's currently in there unless it blows with radio use. Fuses 1, 2 and 4 all go to the radio in some fashion, including the illumination.

The wire gauge is also reversed I think. The permanent +12v used to be for the clock, so it was skinny; while the switched +12v was for the music, so it was fat. New HUs reverse this by having a skinny switched wire and a fat permanent wire. The OE wiring should be adequate, but you might want to consider a separate power line and connection if you're going to use the cig lighter to run an iPod or something, too.

You can also connect your power antenna: blue from the new HU to the Bu/Rd or Bk wire in the car that went to the antenna pin on the old radio. That one can be traced pretty easily to the antenna switch, if you're concerned. It'll be dead until connected to the HU, so that's a tougher one to ID.
