Thank you VU2POP. Is the yellow wire for RX and the green wire for TX and then the 680 ohm resistor goes to ground? Is the LED 12 volts? I was planning on using a Red 3.3 volt LED to indicate TX and a green 3.3 volt LED to indicate RX

Hi ben
See attached pics, solder 2 wires below the K1 relay as shown, then to the Dual color LED , the centre of the LED goes to ground thru a 680 Ohms restistor.
Could anybody tell me a way I can pull voltage from the board for an LED on RX and then pull voltage from the board for a TX LED and turn off the RX LED?
