Hi,Some help needed off someone who owns a Roush car please,I am in the process of fitted a Roush supercharger,but it was not a complete kit,I have managed to make most of the missing pieces by looking at the manual.One thing I cant work out because its not clear in the manual is where do the two ports connect to from the vacuum operated boost relief chamber ,the manual says both to the vacuum harness,I have not got the vacuum harness so it makes no sense to connect both to the same vaccum source,Could someone please trace the path of these two pipes on a car please and let me know.Many Thanks Karl
