ELECTRICAL CONNECTIONS (FACTORY HORN SWITCH)
For vehicles with a two-
terminal factory horn, transfer the wires to the compressor’s terminals. If the horn
doesn’t sound even if the compressor motor turns on, simply reverse the wires.
For vehicles with one-
terminal factory horns, make sure you transfer the wire to the compressor’s positive (+)
terminal. The negative (-) terminal uses a 16-gauge wire or heavier to connect to ground.
ELECTRICAL CONNECTIONS (NEW HORN BUTTON)
Using a 15A fuse (not provided) for circuit protection, connect the positive terminal of the compressor to the
power source.
The negative terminal of the compressor is attached to the horn button (not provided). The other horn button
terminal is attached to any rust and paint free metal to ground.
IMPORTANT
: Both connection must be done with 18-gauge wire or heavier.
