Most if not all cars have a 100-150amp "mega" fuse that run inline with the alternator. If you jump start a vehicle backward or put a lot of amperage through the charging system, it will blow this fuse instead of destroying the vehicles electrical system... well, in theory, it will. At least thats what i've always been taught, never had to change one to find out.
As to where it is at, start at the alternator and follow it back to the firewall. They're usually screwed into it.

Ford deleted the MEGA fuse incorporation many years ago. In fact, 1998 to be exact. Took it out completely. It was a terribly problematic design with the way they worked it in. Nothing dangerous, but caused much havoc. But yea, that was a long time ago. MEGA fuses are used today after market, but much differently and vibration proof.

Yea, you never will lol. Ford uses a a mini fuse (10 I think) inline with the alt harness. Ford tossed the MEGA fuses and opted to split the battery hot right down the middle close as they could to the terminal. They then fused each leg in line and vibration resistant. This is encased in that plastic holder directly in front of the battery between pos and neg posts.

The actuators fit in two slots right behind the door latch inside the door. Remove the bolt with the 11mm head that holds the window track, and pull the track out of the way. Take a long heavy screwdriver and pry the actuator towards the outside of the door. It will take some force, but it should slide off the track.

As far as I know they share the same substructure. You should be fine.
