MOUNTING HORN
(Choose either method Fig. A or Fig. B):
1. Mount the Bad Boy Horn vertically when possible in a dry location, safe from engine
exhaust heat and moving parts.
2. Drill a 5/16” hole at the mounting location. Secure horn with method shown in
Fig. A or Fig. B.
3. Fig A: Install the head of the bolt into the slot of the mounting bracket. Secure the
horn using the lock washer/nut provided.
4. Fig B: Install the bolt into the mounting bracket as shown in Fig. B. Secure the horn
using the lock washer/nut provided.
ELECTRICAL CONNECTIONS USING VEHICLE’S FACTORY HORN SWITCH
5. For two (2) wire systems: If vehicle’s factory horn has two (2) terminals, simply transfer the wires to Bad Boy’s motor terminals. IMPORTANT:
when testing the horn, if the compressor motor turns on but the horn does not sound, reverse the wires.
6. For one (1) wire system: If vehicle’s factory horn has one (1) terminal, simply transfer the wires to Bad Boy’s (+) motor terminal. The
motor’s (-) terminal is connected to ground, any metal body bolt that is clean of paint and rust. Use 16 gauge wire or heavier.
ELECTRICAL CONNECTIONS FOR USING A NEW HORN BUTTON SWITCH (Fig. C):
7. Install the relay provided in a dry location with the terminals facing
downward near the horn.
8. Connect relay terminal 87 to Bad Boy’s positive (+) motor terminal. Use 16
gauge wire or heavier.
9. Connect relay terminal 85 to the horn button switch (not provided). The
other terminal of the horn switch is connected to ground, any metal body
bolt that is clean of paint and rust. Use 18 gauge wire or heavier.
10. Connect relay terminal 30/86 to positive (+) 12-volts such as battery,
alternator, etc. Use 16 gauge wire or heavier. Protect the electrical circuit
with a twenty (20)-amp fuse (not included).
RECAP OF RELAY TERMINAL CONNECTIONS
• Terminals 30/86: the two terminals are connected to 12-volts positive (+) using a
fuse. • Terminal 85: is connected to horn switch. • Terminal 87; is connected to the horns (+) motor terminal

IMPORTANT:
You are required to use the relay supplied with this horn kit to protect the factory horn button switch and wiring. The
original factory horn draws less amperage so most motorcycle manufacturers do not provide a relay in the horn circuit.
2. Remove the two (2) wires from the factory horn.
3. Connect relay terminal 85 to one of the factory horn wires. Note: It does
not make a difference which wire.
4. Connect relay terminal 86 to the other factory horn wire.
5. Connect relay terminal 30 to positive (+) 12-volts battery, alternator. Use
16-gauge or heavier wire. A 20-amp fuse should be used as shown in
Fig. D to protect the motorcycle.
6. Connect relay terminal 87 to the positive terminal at the bottom of the
compressor. Use no less than 16 gauge wire.
7. Connect the (-) terminal at the bottom of the compressor to ground any
clean metal body bolt or the (-) post of the battery. Use no less than 16-gauge wire.
