Did the Connecticut plan of government include what came to be known as the electoral college?

Yes, the Connecticut Plan of government, also known as the Great Compromise, proposed a bicameral legislature that balanced representation between populous and less populous states. While it did not explicitly create the Electoral College, it laid the groundwork for the system of indirect election of the president. This system was later formalized in the U.S. Constitution, which incorporated elements from the Connecticut Plan and other proposals for electing the president.
