Default Npp install?

Hey do any of you guys have a link to the full install of the NPP in a box,I searched YouTube and all I come up with is the mild to wild box install nothing about the vacuum lines or how to use the T fitting. Thanks

I thought that this one was good
The title is about the exhaust but the install covers everything.

I made my own with a vacuum pump and blow off solenoid. Cost me about $50. Can make it loud or quiet with toggle switch.

I’ve been looking for a good video of this myself, especially on how to install the ez-tap connector for an LS3.
The instructions say to run the vacuum line down the middle of the car over the tunnel plate but I’ve seen several posts on here of ppl running through the rocker panel and through the rear wheel well, which I believe is what I’m going to do. Keeping it as far away from the exhaust seems like a good idea.

I finally broke down and yanked the Corsa setup off and put some NPP on my 07!
\What pump are you using? I was looking on Amazon and saw a few for around 30 bucks! I have vice grips holding them shut right now!

Just the vacuum pump, the blow off solenoid ( which isn’t really needed but it allows you to switch instantly between quiet and loud) and a toggle switch.

I used the MAC solenoid valve and the ebay F250 vacuum pump they recommended in earlier posts I found here. I also added a vacuum cannister to reduce the run time of the pump. I'm not sure it helps, but the setup works great and did not have to fight the connection in back of the manifold.
Here is a picture of it on the bench. It all resides in the right cubby. I'll add a lighted switch to the center console where the Heated switch would go if I had them on my car.

Bench setup
Before I received all the parts, I simply ran the hose from the mufflers to behind the passenger seat and connected the handheld vacuum pump to the line. It took a few pumps, but it worked great!!
