i'm about ready to install my hks wastegate and greddy boost controller, and need to know witch port to plug the boost controller in to. the top or the side port???????????????????

 

The top port goes to the COM on the boost controller valve. The side port of the wastegate and the NC port of the boost controller go to a pressure source. Either the turbo or a charge pipe before the throttle plate. Refer to page 10 of the install manual for picture directions: http://www.greddy.com/img/PHP/products/pdf/682.pdf
