I would make the analogy to gunpower. We knew how to make gunpower from raw ingredients for nearly 3000 years before we knew how and why those ingredients actually caused the reaction they do.

I expect it may be the same for consciousness. We'll put the ingredients together (either simulate all the atoms of a brain, or all the molecules, or all the cells, or something higher level) and we'll get consciousness in the simulation.

Like gunpower, we won't know why these ingredients produce consciousness but we'll know they do and maybe later we'll figure out why.
