WV 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.

The site was revamped and Info was lost.
You can't complain if the Info is being offered freely.
* your last Thread was answered by THREE Mods!(https://www.rx7club.com/new-member-r...dvice-1070996/)

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.
