OK, now I'm really confused. It looks like the device you are using replaces the speed control module in the router. Thus removing the wires from the module and connecting them together bypasses the module, and the power goes directly to the motor. Presumably then controlled by the new device you are installing.
The LEDs seem to be connected into the module so most likely won't work after the modification. I have no idea what the red & black wires do, or which small wires are being discussed.
