Well in looking close at your pictures, the connections are not exactly the same, one is going to use a connecter similar to the old Johnson connector with the spring clip retaining system, the first picture almost looks like it has a rubber grommet on it, but I am not seeing the clip grove to retain the connection. All of my Mercuries have been older with the barrel connections, Have you checked with Mercury Marine to see what they have to say? They are a great source of information.
