Review on 🚢 Waterproof 5-Pack Automotive Relay with Harness - 40 Amp 12V DC, 5-Pin SPDT Bosch Style for Automotive Truck Marine Boat Fan by Marvin Nadeau

I used this to drive the fan. So all the wiring can be relatively small thin wires and a low current switch and then use a relay and a heavier gauge wire to power the fan. The fan says to use a 40 amp fuse, which I think is overkill. I don't know what it actually draws, but it doesn't burn out, so its number is less than 40. Very convenient for a DIYer. make a swamp? Installing a fan in a minivan? Adding fog lights to your golf cart? Use your relays for correct wiring.
