When the tonneau is opened (sort of in the center on the inside) is a compartment door that I do not have a clue why it is there or what is might be used for. Any help here?

It could be for the toolkit that comes in the 2004. That sounds like the SSR I saw at the SEMA show with 2004 options.

mystery door

Someone just had to open my door behind the seat
to see what it was. The ECM is located there. I
assume you meant on the passenger side?
