Thanks very much. Unable to get the steering wheel off, but got the emblem off and was able to establish complete circuit. Hopefully, horn will operate correctly once the connections are complete. Life and old cars are a mysterious journey.
Trying to get to the button under the ring. The horns work (removed and hotwired) but, when re-installed, they don't. It appears that the wire from the horn relay to the horn button has been pulled out.
