Rumble motor activated LED by using the rumble motor power we can add an LED that comes on when the controller rumbles. To do this we should check the power being delivered to the motor and plug it into an LED calculator. To find out what the resistor value should be. We find that the peak voltage is at about 2V, this is under the voltage required by our LED so no resistor is needed to drop the voltage. We simply solder our positive and negative leads from the LED to the opposite side of the PCB as the rumble motor connector. .
Run the wires from the LED buttons so they do not disturb the gray rubber pads
Notice the wires coming from the LED start and back buttons
Same on this side but it seems easiest to take the long way around the thumbstick to reach the solder points so this one is quite a bit longer.
Solder the wires to the bottom side of the PCB where the rumble motor connects. In my example red goes to red and black to black. Now when the motors turn on so do the LEDs.
