(They both have the same round connector, but the better design also
has a 2-pin rectangular connector.
There appears to be one round connector with no additional rectangular 2 pin
connector, so it appears that I have the earlier design. I guess it does
work if it stops when corked off. I haven't allowed it to run long enough
to time out, so I'll try letting it run for a while to see what happens.
I'll also have to check the mounting setup again. The football is there,
and maybe, that bracket is the actual mounting bracket.
