You may not have a horn relay if you do not have cruise. I am not sure about the 78's, but 80-up was wired this way.

My 79 does not have cruise, and there is no horn relay either. A 78 would be the same, if you don't have cruise.

In general, a good way to find a horn relay is to disconnect the wiring at the horn, and then push the horn pad and find where the click is coming from. This is a moot point if you don't have cruise.

Usually the aftermarket wheels do ground the wire to blow the horn. In this case, you might have to get a bosch type foglamp relay and wire your own horn relay.
