'95 Spi cooper

ok, i was looking on ebay last night through car parts, and my mum was looking and noticed the air horns and then said theres some in my brothers bedroom.

So, got them out and i remember them being off his civic when he bought it about 5 years ago or something.

Right, there is 5 different sized horns (i never heard it play) and the compressor. They all colour co-ordinated tubing for each horn to compressor.

The compressor has + and - connectors on the back. Now how and what do i connect it to to hear it? lol

Any help would be great, i want it set up for sunday's show!

Find somewhere to mount them - which may be easier said than done!
And then wire them up to what I guess will need to be a 12V live source.

ye i got no spare in a spi engine bay!

to turn it into a switch, do i just gotta put a switch into one of the connecting wires?

Compressors for airhorns suck quite a bit of juice, so best use a relay to feed the live power to it.
For testing you can just connect direct to the battery, but for a perminant fix use a relay. The main power feed for the relay would be best coming from the live side of the solenoid.

This is how I fitted my standard airhorns but wirings the same for musical

I have seen thenm mounted on brackets on rear subframe before !

[wilcooper]

right, problem now is, they work but i have no idea what firing order they are in, there are 5 horns, and tried lots of combi's but cant find it, anyone help?

[miniman retford]

Do they go in size order ?

[wilcooper]

you got different horn sizes, tubes and the connecting ports on the compressor. thing is, they are supposed to be colourcoded, but there are only two on and im not sure if those are even right!

[Dan]

Yes they are colour coded, there are rings of colour around the ports on the compressor and on each horn. Use the hose to connect the horns to the correct coloured outlet.

You are pretty much guaranteed to be arrested if you use these on the road.

So, is there a decibel limit for car horns?
I was thinking of running this:

on my Cooper around London, because I am sick of stupid tourists and general muppets walking out into the road with out looking!!!

[Dan]

Not as far as I know but horns must be monotone. They must produce the same note evenly all the time they are sounding. Musical horns are illegal on the road.

[BadgerBaiter]

Ah ok

Marvellous news for me then I think ! Shame about the tourists.

I guess you have to keep the musical ones for shows etc?

[wilcooper]

Yes they are colour coded, there are rings of colour around the ports on the compressor and on each horn. Use the hose to connect the horns to the correct coloured outlet.

But mine doesnt have colour coding on them like i said.....theres only blue and yellow, and im not sure if they are right!

You are pretty much guaranteed to be arrested if you use these on the road.

Only if heard by the police and i'm not stupid.

I want them in for a bit of fun at British Mini Day.

So could anyone help with what goes where? 5 horns different lengths need connecting. Just need a lil diagram if someone has these.

[lrostoke]

real long shot but try going on ebay searching for musical air horns and see if any of the pictures match.

example this one

shows the colours for the various horns, and a close up of the compressor..
