Dave,
Based on the 74 schemetic, the purple/black is coming from the button and
should be connected to W2. If it has ground all the time, it's shorted out, as
the horn-push should send ground to this wire. The purple wire should be
connected to W1 & C2, sending 12v to the relay, and the purple/yellow connects
to C1 sending 12v to the horns when the relay trips.
Alot of us probably have the worn column bushings that cause the horn to beep
when you're pushing hard on the wheel. Like someone said, it grounds out and
then sends ground down the purple/black wire.
good luck,
Sloane :)
