| otherwise follow some of the vac lines that are hooked up to determine if its the AIV or the EGR solenoid then I can try to help you from memory. Somone correct me if I'm wrong but I believe its AIV: Top port - Connectsx to a nipple on the balance tube middle port - to the AIV ( I believe through the upper hard pipe galley on the side of the upper plenum) Bottem port - to the top port on the EGR solenoid EGR: Top port - From the bottem port on AIV solenoid Middle port - To the EGR on the back of the moter Bottem port - connects to the lower hard pipe galley on the side of upper plenum and then to the nipple on the lower passengerside IC pipe, or possibly to the up pipe off the turbo.
