An LED light is visible on the Zt-3 between the "Data" and "O2 Sensor" connector locations on the Zt-3.  When initially powered the LED will be a solid light during oxygen sensor warm up.  Several seconds later the LED will begin to flash to indicate data is being transmitted on the serial data output.
