A point of clarification about fuses. There is no way too big a fuse will, by itself, hurt your electronics. The issue is just they will not protect it either. If your electronics develops a problem, the purpose of the fuse is to blow protecting it and the car from seeing too much current thus too much heat thus risk of additional damage. A 10amp fuse on a 1 amp load will not blow until you have a mess. But the fuse should never blow anyway. It takes another issue before it makes any difference.

Another factor is the size of the wire. If it will not carry the load the fuse will permit, it will overheat and become a hazard. But again, this is only a problem is something else goes wrong.
