For the horn, iirc, and off the top of me head.....
Power to the horn is a pink wire found in the stock loom, activated by pressing the horn button which then grounds to the handlebars to complete the circuit. Where the pink wire gets its power from would be the horn relay thingy....

Yes, the horn button provides a path to ground, so you will need to connect that green horn wire to ground inside the headlight bucket. There should be a couple multi-pin ground connections in there. The black wires feeding them run back to a ground connection somewhere on the main frame. The bucket itself is not a suitable ground connection because it's rubber mounted, plus somewhat isolated from the frame because of the greased steering bearings.

Hi chinny,
wiring the stock horn like they said will make it work OK.
Wiring a horn that's loud enough for a car driver to hear takes a relay.
I use a Stebel-Nautilus mini air horn. It comes with a relay that has a wiring diagram on it.
