How do I connect the power source to the Chron-O-John?

Hint 1 of 4:

The power cord on the John isn't long enough to reach the basement by itself.

Hint 2 of 4:

But you might find a way of extending it.

Hint 3 of 4:

You'll find something on the second floor of this "motel."

Hint 4 of 4:

Get the extension cord out of the room where the mummy is.
