Can anyone tell me if I can use the existing horn circuit or do I need to make a new one? The instructions I have are rubbish! It's one of the roadster horn kits off eBay. Cheers
 
Existing wiring should be ok, unless the kit has a massive current drain, in which case you might want to set up a relay

Regret not familiar with the roadster kit to advise more
 
What is the horn called that's like 'the masks' eyes poping out hen he sees a hot bird. Aaahhhooooooogggaahhh if you get me? Haha :)
 
i always thought it was illigal to have air powered horns on cars..?

That depends apparently ....

Single tone air horns are legal on any car.
Musical/multi tone are legal only on cars pre 1974 .....
Apparently twin tone horns that play both tones simultaneously are classed as one tone so are legal on all cars.

The above info is just from a few modified car sites as I haven't been able to find anything on .gov sites
 
yu need an on/on switch and a 10A fused relay....

Surely you only need an on/on switch if you want to install the air horns as well as continuing to have the option of using the original horn. If the OP just wants replace the original horn with the air horns (providing they are the road legal version) then he can continue to use the original horn switch into a relay?
