if you read thru kline conect mod b directly on mcu,I think it is pin 22 but I am not sure

Did you use external power, this will also do the job.

Problem is with your k line adapter,read my old post, you also have to connect the adapter upside down , not like the picture,which i forgot to mention, previously.also no need for external power.
