To check the lighting functions of your trailer connector using the Tekonsha # 6562 Trailer Emulator, plug the unit into the 7-way and activate the lighting functions (right turn, left turn, brake lamp and running lights) one by one. As each function is activated, the corresponding LED on the tester should light.

As for the BK lamp, I'm assuming you have a brake controller installed. Modern brake controllers send a pulse back to the trailer connector to determine if the trailer is plugged in. This would make it appear that the LED is flashing.
