4CARS Dual-Tone Snail Horn with Relay 12V

Dual-tone HORN, 12V, powerful sound.

The right solution when the original horn is unsatisfactory or not loud enough. Includes bracket, screws, and relay. We recommend leaving installation to a professional.

INSTALLATION:

Choose a suitable location inside the engine compartment (the original horn location or near it) that is as protected as possible from water, dust, oil, and is as far away from the engine block as possible. Secure the horn firmly with a screw to the body.

ELECTRICAL CONNECTION:

All connectors must be connected with 2.5mm diameter cables. Connect the horn's (-) terminal to the negative pole (-), e.g., to the body, using the shortest wire possible. Connect the horn's (+) terminal to relay terminal "87". Connect relay terminal "30/51" permanently to (+)12V via a 20A fuse. Switching against the negative pole (-) chassis. Connect relay terminal "85" to the chassis (-) and terminal "86" to the (+) of the original horn. Switching against the positive pole (+). Connect relay terminal "85" to the chassis (+) and terminal "86" to the (-) of the original horn.
