Default Opti vacum line relocation

95 T/A

On my original set up their was a vacum line from the opti to the TB intake elbow.

Now I have converted to funtional ram air like the 97 WS6. Where should I relocate the vacum line connection that used to go to the intake elbow . Currently have it located in the far right hand corner of the airbox if your facing motor. This connection should be used for the air pump, but I deleted the air pump and pluged the hole with a vacum cap. Put a small hole it and inserted the opti vacum line connector. Is this a sufficent place for this or should I relocate it just in front of the TB in the silicone coupler? I would "think" it would be able to draw more vacum faster being located in front of the TB, but I'm no expert and not sure if that is important. Anyone got a 97 WS6 funtional ram air set up that can tell me where theirs is located?

I would just put it in the silicone adapter in front of the TB and call it a day.

As long as it is somewhere in the intake path, you are good to go.

I drilled a hole in my smooth bellows and put the vacuum connection through there
