Fuse holder installs in series with the +12V supply line.

SCHEME 1: Common fuse for valves operated from single DC line: Connect between battery +12V to system master switch input. If Master switch is not used connect between battery +12V to the outgoing DC line to valve/s.

SCHEME 2: Independent fuse per valve: Connect between master switch +12 V output to each outgoing +12V supply line to valve.
Barrel or butt crimp-on splicing connectors are recommended to connect the wire ends.
Other connection methods may be used as long as connection is solid and secure.

Fuse holder is meant to be installed in a protected but accessible area or compartment, not exposed to water. If water exposure is expected and inevitable use a waterproof IP 66 rated holder available from most auto stores.
