I lost mine before too. I had it tapped into th K&N on my first design cold air kit. Well the K&N and the pipe got seperated (they were arguing to much) and the K&N took the ATS with it. I was NOT about to pay 40 bucks for one so I went to the Junkyard and found a couple off some 80's gm cars. They were pretty much universal in my digging so I got 3 for the total sum of $0.00!! When you go to the junkyard with a whole toolset and come out with three little screw like things and some wires (connector), they generally let you through. I have gotten more then a few small items this way.
