Is your battery oriented correctly? I can't remember how my 2008 was but it seems every picture of engine compartments the battery is turned 180°. Posts toward the front of the car. Maybe I'm having another senior moment...Got some things done before ShelbyFest

Found out there was already an adapter on the shifter for the black ball, so then it was easy to get the new one on.

Got the connections for the Battery Tender, as I discovered 3 weeks of sitting is enough to drain the battery. So now it's a lot easier to connect it when I park it in the garage.
