MSD relay modules are designed to be easily installed in most automotive electrical systems where a high amperage relay is needed. These relay modules are perfect use with high amperage electric fuel pumps and high CFM electric cooling fans. Each relay comes with a 40amp fuse, however lower amp fuses can be installed if required. The relay housing comes with a labeled lid that snaps into place providing a clean installation, and protecting the main power stud and triggers from contamination or accidental contact.LED status indicators, show you which channel is triggered at a glance7V to 20V supply to fit a wide variety of applicationsConfigurable single-wire activation with Ground (-) input or 12V (+) input, with removal of the Tie-BarRemovable cover for easy accessibilityLow profile JCASE fuses provide ample protection in case of a shortIndependent 40A outputs, to supply power to most aftermarket fuel pumps and electric fansDetails:Emission Code: 5Warranty: Manufacturer's Limited 1 Year Warranty
