PIAA SPORTS CAR HORN - Installation Instructions

Please read this entire manual before installation and use.

Your specific installation may require additional wiring connectors that are commonly available.

1. Do not remove or alter the screw or the bracket on the backside of the horns. Doing so may alter their performance or may disable them.
2. Install the horns so the open end with the cover points down.
3. Do not install and wire the PIAA car horns so they work with the factory installed horns. Doing so may overload the circuit or may not pass local noise regulations.
4. Install the car horn in a location that will not get direct water spray or dust.
5. Install the PIAA Sports Horns in a location that is away from hot engine components.
6. Do not paint or apply any type on chrome plating or powder coating to the PIAA Sports Horn. Doing so may alter the tone or function of the horn.

INSTALLATION:

Locate the factory horn(s) and determine what type of installation is involved. There are four warning installation scenarios (A,B,C,D), study each one and determine which one fits your application.

When mounting the PIAA car horn, mount them to a sturdy location with minimal vibration. Use a suitable fastener of 8mm (5/16") or smaller.

INSTALLATION TYPE A:

Two factory horns with tow ¼" blade connectors each.

1. Unplug the factory horns.
2. With an assistant to honk the horn use a test light or voltmeter to determine which wire is positive (+) and negative (-).
3. Connect the positive (+) wires to the top terminals on the PIAA Sports Horns.
4. Connect the negative (-) wires to the bottom terminals on the PIAA Sports Horns.

Single factory horn with two ¼" blade connectors.

Parts needed: Four insulated ¼" female blade connectors, approximately 5-6ft of 16AWG insulated wire, two splice connectors.

1. With an assistant to honk the horn use a test light or volt meter to determine which wire is positive (+) and negative (-)
2. Cut off the factory ¼" female blade connectors and splice two lengths of wire to the factory positive (+) horn wire. Make sure the lengths of wire will reach the mounting locations of the PIAA Sports Horns.
3. Crimp and insulated ¼" female blade connectors to the end of each wire that was added to the factory positive (=) wire. Connect these positive (+) ¼" female b lade connectors to the top terminals on the PIAA Sports Horns.
4. Cut off the factory ¼" female blade connectors and splice two lengths of wire to the factory negative (-) horn wire. Make sure the lengths of wire will reach the mounting location s of the PIAA Sports Horns.
5. Crimp and insulated ¼" female blade connector to the end of each wire that was added to the factory negative (-) wire. Connect these negative (-) ¼" female blade connectors to the bottom terminals on the PIAA Sports Horns.
