I just installed the series IV Saleen supercharger onto an 03 Mustang GT. I have 2 questions,


#1 where does this vacuum barb that is sticking out on the back of the supercharger at the top of it on the driver side plug into? I have tried plugin it to the EGR selenoid vacuum line and it makes the car idle rough. Next I tried plugin it to the fuel rail sensor and boost valve t-line assembly and I get a check Engine light but it don't run or idle rough off of that. Can you please help me on this problem? If I leave it unplug it runs fine but I am concern about dirt being sucked into supercharger onto the blades.

#2 where do you plug the boost gauge that reads boost psi at on this charger?



Thanks for all your help.

 

Is there anyone out there that owns a 2002-2004 saleen mustang with the series IV supercharger that can pop there hood and help me by looking at there vacuum lines and telling me how they route onto the supercharger, EGR Selenoid, EGR tube, fuel rail [ressure sensor, and the supercharger bypass valve, etc...

 

Nevermind you guys I figured it out. For those who is having the same problem this is what you do. The stock plastic red vacuum lines going to the EGR Tube, EGR selenoid, fuel pressure sensor, and did go to the old stock throttle body, you had to remove the old stock throttle body wire and discard that, take the end of the fuel pressure sensor plug off the wire discard that, take the two into one connector that was on the other end of the throttle body red plastic wire plug the single end into the bard on the back of the supercharger run the line from the passenger side into that 2 into 1 connector and the extra red vacuum line that you have also plug it into the 2 into 1 connector run it to the driver side into the bottom EGR selenoid bard and the top bard on the EGR selenoid plugs into the EGR tube (which is the satellite dish or flying saucer looking device). You know have a complete connection of your vacuum lines.
