I don't have one at the time but the horn themselve are located in front of the radiator. The low note is behind the head lights and the high note horn is mounted on the frame in between the head lights. Plus this location should be approximetely the same for a 78'.

It will be in the fuse box maybe under some other name which is on that circuit. Get a wiring diagram from MOTORLIT.COM and it will show what fuse the horn is on. The fuse is hidden in the center of the dash above the radio. There are three fuses and the horn relay is next to these fuses.

According to the Assembly Manual it should be just off the I/P wiring harness under the dash near the fuse panal assembly.
