I have a 2002 protege. It took me a long time to search for the horn cable. The horn is infront of the radiator, between the grill and the radiator on the passenger side somewhat near the head light. The cable is under the metal frame above the radiator. Take out the grill if you can't see the horn cable, you just need to use your hand and follow the cable under the metal frame.
Different make and model might have different place for the horn.
