Fuse size to use

I rewired my Duster and spilt up the circuits. The original fuses were the 6 glass fuses. I rewired the car myself. I built my own wire looms and connectors. I spilt my wiring into 20 fuses ranging from 3 amps up to 20 amp. Plus I replaced the fusible link with a 30 amp fuse located in the engine compartment
