Newer (like after 2006) Fords are staring to migrate from GEM to something called the Smart Junction Box. Sort of like GEM on steroids.

The point is, it is driven by a processor and it does "wake up", "look around", possibly "exercise" some things and then go back to sleep on a "regular" basis. I can't be an more specific, but this will happen continuously.

In "theory", this current draw should be low enough and infrequent enough for a full charged battery to last 2 weeks without starting the car. After that, get out the jumpers.
