i have a new universal wiring harness and it says that 10 amps are put on the gauge power. Auto meter says to use 4 amp fuses inline..... which basically means they will blow as soon as the car turns on. Is there a way to reduce it to 4 so im not replacing fuses all day.

Thats not how it works. The fuses are there to regulate how much power the device is drawing on use. So if the autometer shorts or what ever it will blow the fuse to protect the unit. Leave the 4 amp fuse in line at the device it will be fine.
