Is this a EC300 Horn?

MOT coming up on Monday, just trying to get the small pieces together.

Is this a EC300 horn? Came in a shopping-bag when I bought the bike.

The serial nr is Maruko, SM-70, and Toyota RAV-4 also uses it, as I googled it.

1 plug that dont match any on the wiring-loom ive got. Porbably power? What wire is this? And the horn is then just connected to the frame for earth I suppose?

In this specific horn, I suppose so, but also in general, yes. I just found out that the regulator just holds the tone of the horn steady, and I am passing the MOT without a steady "tone".

- So no regulator. Buying a new horn tomorow with two wires on.
