When you depress your horn button you are picking up the negitive side of the horn relay. So your relay is wired as follows, the positive side of relay coil to hot positive source ( unswitched ) negitive side of coil to the steering column ( horn button ). Relay side of horn relay, postive in ( for horn ) to ralay, positive out to horn its self. Horn will pick up its negitive source through the car frame when mounted.
Hope this is some help.
