Sorry, I don't have any pictures, but the trunk lid release motor is in the lower trunk valence on the passenger side, it has a 3-pin connector (only 2 pins are used), called out as C844 in the wiring schematics, it should have a Black wire, which goes to chassis ground somewhere in the vicinity, and a second wire, Orange w/Green tracer, that you apply 12V to, which activates the trunk release motor.
The Ford wiring diagrams show the Orange w/Green tracer wire going all the way back to C451A on the Anti-theft/Central Locking Module, which is in the vicinity of the passenger-side A-pillar.
