*by M***B on December 31, 2025*

I got them today. They look good and the internal wiring is good quality. I have to 525 Walbro Hellcat pumps that pull 15-25amps I've burned up a few relays because of the amperage. So hopefully these will be strong enough. Gonna up grade my wiring with the included copper eyelets and see how they hold up
