wiring a horn,relay,and fuse

[awesome]

I am installing a horn on my atv and i am using a fuse and relay. now i have it all hooked up and i tested it with just that to battery so it would not mess up my atv from a short or something but when i press the button i hear the relay fire so thats good BUT no sound from the horn

Here is how my wiring goes
horn to #87 on relay
horn to neg on battery
relay #86 to #30
relay #30 to fuse(25) to pos battery
relay #85 to horn switch
horn switch to battery neg

( i hooked both neg wires together to make on to neg post on battery)

this is a 12v/30amp relay

on the horn and horn button there is no marked + or -

if anyone can help that would be great
