Fuses on relay board, over amped Options

[Tom]

I have followed two AAR shorts the past 12 months that caused extensive damage to the ignition harness in both cases. Just read a thread on a member losing his car to a fire. Don't know if this was AAR related or not.
Some things I have learned.
The first fuse ( rated at 8 amps) is not being used. Goes to pin #9 of the 12 pin connector at the rear of the relay board.
The second fuse is 25 amp, and fuses the heated blower, fuel pump, AAR, and defroster for rear window.
The heater blower draws about 5 amps, haven't measured the fuel pump- probably near the same, AAR draws less than 2 amps, probably the greatest draw would be the defroster.
Most don't have the rear defroster, so a 25 amp fuse isn't necessary if all is working properly. A 16 amp would do the job and probably blow before a fire in the harness if any one of the loads became shorted to ground.
What are your thoughts and knowledge about this?
Since the front fuse isn't being used, I'm thinking of moving the wire for the AAR from pin 12 to pin 9 and using the front fuse for the AAR. If I do this I will mark the fuse as AAR and I will make a correction to add to my car's Haynes book to note the changes. I will use 8 amp fuses for both.
OK, let me know what you think.
