does any body have one of there on thier 4th gen cars? i was reading about them but i cant figure out if it is just a blank male and female plug where you disconnect the wires and plug in the blank just to keep the wires and soloniod clean or if there is actually electronics in the thing?? im not sure cuz i cant justify 30 bucks on something i can get from napa for 3 dollars!http://www.motorsporttech.com/fbody_drivetrain01.asp
