When you removed the rear left trim section beneath the cargo floor...you didn't see the TCU/ULF unit mounted to the bracket at an angle?
If you didn't remove #6 in the diagram below...which is the plastic piece mentioned above...there are 3 or 4 nuts (#4 in diagram) that secures the piece to the vehicle...once you pull it up & out of the way, it should expose the TCU/ULF mounted at the bottom of the rack that is on the left side:
Here's another image (from Xoutpost) of the TCU/ULF location...remove the black plastic piece that is at the far left (of the floor) and at the base of the component rack...you can see the very small "silver" tip of the TCU/ULF sticking out & a purple wire at the far left corner of the cargo floor (where it meets the side trim of the tailgate):
Once the floor piece mentioned above is removed (the painted blue area & wires below is where the black piece was), you should see the TCU/ULF unit (the silver component below the CD changer & at an angle...there should be a label somewhere on this component that will have the PK code:
