the factory horn wires. Note: It does not
make a difference which factory horn
wire is connected to terminal 85.
16. Connect relay terminal 86 to the
other factory horn wire.
17. Connect relay terminal 30 to
positive (+) 24-volts such as the battery,
alternator or fuse block, using 16-gauge
or heavier wire.
WARNING: The 15-
amp inline fuse provided must be
connected directly to the power source.
18. Connect relay terminal 87 to the compressor’s positive (+) terminal. Use not less than 16-gauge wire.
19. Connect the compressor’s negative (-) terminal to boat’s negative (-) battery post or any clean metal
negative surface. Use not less than 16-gauge wire.
