Magnum Stebel II horn consists of 1 High tone and 1 Low tone. It is an electric horn and not an air horn. Hence, it is legal with LTA. Many thanks to my friend Johnny Tan who has helped me with the installation. We made use of the stock horn power input line for the Magnum stebel horn. The stock horn is simply too soft. Just like a scooter horn.


Diagram from forummers on how to fix up the Magnum Stebel II Horn.

We fix the horn without the relay. It should not be a problem as long as we don't press the horn for more than 5 mins continously.

These are the diagrams which we analysed and plan out our materials before installation. Many thanks to toyota forummers for their advice and on site demo of their installation.
