That link to Amazon takes me to relays rather than fuses!. And the relays shown are not what you need. You need ones with a diode across the relay coil, to protect your ecu against voltage spikes .
Better to search ebay for “12volt diode relay” as a greater choice on offer. To distinguish, you will see on the diagram etched onto the relay casing, a diode symbol (like an arrow head with a line across the tip), in parallel with the relay coil.
