Need help, what is this?

Does the boat have I/O? reason I ask is the blue wires typically are associated with outdrive position/sending units. the violets are also associated with boats with trim pumps ( lifting an outdrive) and the yellow could be an extra wire from an older wiring harness that was used on engines with carbs instead of EFI. Good luck.
