i recently purchased a tactrix and an XPT stg 2 tune. the tactrix came with the white 03-05 connector and the blue 02 connector. just wondering where i plug the blue connector in? i know the test mode connector gets connected and i plug the obd2 end in. but i am stumped when it comes to the blue connector. i think its due to the fact that the blue connector looks like the 2 green test mode connectors... HELP!

it is located under the stearing up next to the green connecter.

got it thanks man

You can leave the connector in the car all the time, but make sure to disconnect the green test connectors before you start the car.
