Is it me are they too high beepy-ish sounding?

The Supertone horns are 300 and 500Hz and are definitely more "European" sounding than the typical American car. For a more "normal" sound, you want the Sharptone horns, which are 300 and 415Hz and sound closer to OEM. It's kinda weird that the Supertone sound is sharper than the Sharptone, but there you are.

Hello, i just bought this horn but I'm wondering how can I see which is positive terminal and which is negative? Two terminals look the same to me

When looking at the horn from the back, the positive terminal is on the left.

These horns fit 2007 honda pilot awd ? do i need new wiring harness ?

I have them on a 1990 Toyota Landcruiser and I used the existing horn wiring. You may have to modify something but I bolted them right to the grill frame and wired them up. They work great and for the price, you can't beat them. Have fun!

へんな音・・・・

くぐもった感じの変な音だと思います・・・。音圧も普通な感じ。まあ、好みの問題もあるでしょうが。但し本気で水に強いです。直接水掛けて洗っても平気です。バイクで使うと、鳴らしている間はヘッドランプが暗くなります。色は良いので、見てくれは良くなりました。
