Bob,
Looking at your pic, it seems like the relay is turned with the 3 terminals pointing upward (just the opposite of mine as explained above) and from what I can see it looks correct with.... the wire from the steering column/horn button is connected to the left terminal, power wire connected to the center terminal. The two positive wires coming from both horns are connected to the terminal on the right.
