So I am getting closer. It appears for the 25 STX what need to happen is from the C408 plug (pins #28 & #31) I need to install 2 pinned wires into this harness (truck side) and run them to the C2280E plug at the ECM. Specifically pin #8 & #9.

That shouldn't be hard to check. If you still have everything changed with forscan. One of the pins in C2280E should be a momentary ground. If you tap that to ground then it should trigger power to the other pin and turn on the lamps in the chmsl.

Pin #8 specifically states bed/cargo
Pin #9 says not used. Thats the only thing that im confused by. Read what's in above the pic of the ECM connector diagram.
