I'm not quite sure what the A.T.A. means but if you can send me a picture of your 7-Way connector I can see if it's something that we are familiar with.

The 2 most common 7-Way connectors that we know of for trailer wiring are blade style like part # PK12706 or round style like part # PK11700. I have attached a photo that shows the typical wiring configurations for both styles and what they look like that you can reference as well as a link to our wiring helpful articles. You can use a circuit tester like part # PTW2992 to test the functions of your tow vehicle 7-Way and then a 12V battery to test the functions on your trailer side 7-Way to make sure they match up.
