Horn wiring help needed

Hey guys, I don't post too often on here, but I have a '65 Bonneville that's been hardtailed, (no wiring loom or harness), I need to get her through inspection, so I bought a dinky Kawasaki horn just to temporarily hook up. I'm having such a hard time with it, I used this diagram (attached) with a 20A fuse, I understand that the bike is positive earth, so I hooked the fuse and terminal 30 to the negative terminal on my battery rather than positive. No dice. I'd appreciate all the help I can get. And the appropriate slap to the face for getting it wrong.

I think the relay is wired wrongly. Terminals 85 and 86 are the relay coil. Try it the way I've re-drawn it below, although for a small electromagnetic horn you don't really need the relay, ground the battery positive, run a wire to one side of the horn, the other side to the horn push and the other side of the push to ground.:

Is that a 6volt bike and you are installing a 12v horn and relay?
