If I remember corectly, on the battery terminal of the voltage regulator, you should have 2 wires-- one goes to the ammeter and the other is the power to the horn. Kieth is correct that the horn button provides the ground when pushed. You should have power to one of the horn wires all the time.
You need to get yourself a volt/ohm meter-- it will make your life a whole lot easier with the electrical part of your truck.
