Its labeled when you open the fuse box.

If its not working...

With ign off, press horn, if you hear relay, its probably not the relay.

Usual place the wiring fails is about 1cm from the connector into the horn. Additionally, the horns aren't particularly reliable units.

Horns work direct to battery.
Checked the wiring.
Nothing from the 5 relays in the fusebox.
So looks like relay. Thanks again!

Bottom right of the cabin relay box, just below the diagnostics connector
