Bosch Europa Horn Installation

Has anybody tried to install Bosch Europa's?
I just got mine and noticed that the connectors do not indicate polarity for positive and negative.
Are they interchangeable?

may polarity po yan. btw hindi lang tutunog pag nagkabaligtad - no need to worry.

hmmm... yung europa ko parang may + - ah?

anyway tama di nga tutunog yan pag baliktad just make sure meron kang inline fuse at relay

And make sure you mount it on a spot where it won't be exposed to water too much... that horn model is sensitive to getting wet (but i love the sound).

ala polarity yan. use large gauge wire pra maganda tunog masmaganda kung tig-isa na relay habang naluluma kc yan naghahanap ng mataas na current eh
kaya ung iba nasisintunado na at pagrainy season alagaan mo ng WD-40

Slightly OT, do you know the frequency of those horns? The one we bought na standard Bosch "pit-pit" have 420Hz and 335Hz for the high and low tones respectively. TIA ;)

Thanks everyone for your inputs.
I started my installation yesterday and did a few tests and here is what I found.
1) The horn's metal parts cannot be grounded.
2) The terminals must be connected to + and - connections and are interchangeable.

mbeige, in answer to your question, the horns frequencies are 300Mhz and 375 Mhz. I have heard of some people fine tuning and adjusting the horns to a higher frequency but haven't yet discovered on how it's done.
