After Market Universal Wiring Harness & Fuse Block?

no MADD here, i'm still running the ammeter, which i opened up, inspected and made sure the connections where tight. but like Cuda416 say's, the direct current to feed big load items (H4 headlights and A/C), gets fed through relays, and so have their own inline fusing. however, the power to trip the relays, the dash lights (LED's), the gauges and tail lights are still on the load side of the ammeter. i don't have anything else electrical, mechanical fan and fuel pump, and stereo by TTi
