This is the Trim Advisory Board, located on the Starboard side of the engine room. It will quickly show you which trims are active, but it is unlabeled by default. For convenience, I have labeled it. Every rectangle represents a lever, while every circle represents a valve.

Here are the starboard trims, labeled in relation to the labeled Trim Advisory Panel above. It is important to note that "B" is a lever on the back side of the void drive, and is easy to miss.

Here are the port trims, labeled in relation to the labeled Trim Advisory Panel above. Please be aware that lever "D" has a misaligned hitbox, and can only be interacted with from the bottom of the model.
