horn drama

Situation: A 64 bug: I have been renewing the front suspension and steering: new beam, steering box, etc.
Yesterday I installed the steering box and put a new coupler; I connected the battery to check if the horn worked...and it did, but all the time!
It must be said that this car does not have the original horn, it's a different type and it's ran from a relay, as fas as I can say it works connecting a terminal of the relay to ground (there's a cable running from the steering column to the relay, if I disconnect it the horn does not sound)
I checked the brown cable running inside the shaft and it is intact, I took out the steering wheel and the horn kept beeping!
What could cause this kind of behaviour? I don't know what else to check!
I haven't messed with the column at all so I don't see how it could be grounding now

If you hook the brown wire to the terminal of the relay you grounded it should sound the horn when you press the horn.

well, problem solved, I put back the old coupler and the problem went away, it doesn't make much sense but the new (brazilian) coupler made electrical contact between the steering shaft and the box :evil:

dumb question..

I've had this mysterious issue with asian and brazillian couplers -- anyone know why this happens.
