I think you need it for window operation. or seat if you have an electrical seat
Its called a multifunction relay.

Which car ?
Picture would be nice, but not required.

If your car has memory seats I would take a guess towards that
being the controller for the seat memory.

My car only has power seats and has no devices under the seats
except wire connector for power motors.
