 ### Preparation
 
 1. Disconnect the remote device from power (battery/usb)
-2. Add a resistor from yellow wire to the one end of the LED (either end of the resistor is OK, either end of the LED is OK)
-3. Add the yellow wire from a GPIO pin that will not cause any issues (ex: for TLoraV1, we can use GPIO21)
-4. Add the black "ground" wire from the ground pin on the device (ex: for TLoraV1 it is the end pin next to the RST button) to the other end of the LED
+2. Connect the resistor to the longer (positive) lead of the LED and the yellow wire to the other end of the resistor
+3. Connect the other end of the yellow wire to a GPIO pin that will not cause any issues (ex: for TLoraV1, we can use GPIO21)
+4. Connect the black "ground" wire from the ground pin on the device (ex: for TLoraV1 it is the end pin next to the RST button) to the shorter (negative) lead of the LED
 5. Power on the device
