Wire colours for the Horn wire to the steering Wheel.

[Trollboy-1950]

Does anyone know what the wire colours are for the wire to the horn button. I had some Redarc gauges installed and horn not working. I have found 2 wires that operate the horn but I cant figure out which of 5 - 8 wires could be the one without triggering the Airbag 5 or 6 wires go into the wiper for the associated horn button cruise control etc.
