The '08 and '09 models had 10 amp circuits for accessories while the 2010 and later C-14's (GTR's) have 5 amp accessory circuits. You have the later model and the lower amperage circuit.
You should never replace a fuse with a larger value fuse, in any circuit (vehicle, house, commercial, wherever). That said, changing a 5 amp to a 7.5 amp probably would not be enough to damage the wiring in the event of a short.
As others have said, the best way to approach these things is to actually measure the current (amps) being used- it is entirely possible that a 5 amp fuse will be enough to run your heated seat as long as there is nothing else on that circuit. Maybe you could find someone who could help you out regarding the current measurement- perhaps even a friendly dealer would do it without charging you anything. As the dealer will (or should) have a current meter already the actual test will only take a few seconds.

Hi All,
Got my Corbin seat yesterday with the rider's set up as heated.
The instructions show removing the 10A "Accessories" fuse and replacing it with Corbin's 7.5A inline fuse.
Problem is the Accessories fuse on my 2012 Australian 1400GTR was a 5A fuse, and was also stamped as such on the fuse box cover.
Any issues anyone can forsee?
Thanks in advance
