I did see some posts about this but nothing specific unless I missed one. I finished installing a Kraftwerks SC kit and I am still a bit confused on some of the vacuum lines. I posted some pics so you all can see what I am talking about. The installation stated to install the IAT to the intake pipe going to the throttle body, I did do that, but now there is nothing connected to the vacuum box. Is the vacuum box and bypass control valve needed or can the vacuum lines be routed some other way?

Hi everyone,

I am replying on this because I am wondering if I posted this in possibly the wrong area or if I did not ask the question correctly because I am not getting any responses?

please let me know, thanks!

Did you accidentally plug the vacuum control vavle electrical connector into the IAT sensor?

Thanks for the reply Billman250,

My S2K previously had a CT air intake on it so not going from stock to the SC install there were things not in the places the SC installation said they would be which is understandable. The instructions only told how to install the IAT into the intake tube but never said anything about the connector or where it was. My vaccum control connector is the only connector in that location. I am not seeing any other ones to be able to connect to the IAT. I do have on the way a part to eliminate the vaccum box, selenoid, and secondary air pump, but now I am wondering if its possible there could be another connection for the IAT I am missing. Any thoughts?
