s4 to s5 intake swap vacuum route
 

I have been searching over a week and figured out most the swap without finding much info because all the threads are dead or the photos cannot be viewed anymore. I have deleted the OMP And all other modifications are done. I just need a guide on the vacuum lines, BAC, and what do I do with the solenoid switch that is in the way of the UIM? I heard someone mentioning being able to hook up the VDI without an rpm switch, if not I'm just gonna keep it open till I get everything else situated and driving.

Will the5th and 6th ports operate normally with a stock exhaust manifold, catalytic converters and a 3in borla catback?

Thanks in advance.

Kenneth.

Is this site dead or something? most links are old and dont work, forget about pictures that work and I never get any feedback.

The site was revamped and Info was lost.
You can't complain if the Info is being offered freely.

What exactly are you doing with this engine?
is it an s4 with an s5 upper that you do not want to have an air pump on?

Take a look at this writeup. It answers many of your questions.

Just follow the s5 vac diagram. You'll just have to hodge podge a couple things line the bac air line because there isn't a stock component that works between the two intake versions.

Best way to actuate everything is following rotaryrocket88 's writeup using rpm switches.
