I have my new FW and was wondering when parked over night say in a Walmart lot with no power source do you leave the FW plugged into the truck and does it draw off the truck battery?
Old Biscuit, on the newer Fords, the top (indent) is at the 3 o'clock position. So yes, you are correct, if the plug was installed like picture, the battery/charge would be at one o'clock.
The Fords have the 4-pin, and 7-pin, side by side, their reason for doing this. I actually like being plugged in with the door on the right, rather than the top.
