Ebay forced induction products...

I went through the same thing with the wastegate when i helped my friend turbo his truck. we were sitting there for a minute scratching our heads, my friend was about ready to put it on like that. I went and dug deep in the box and found it like wedged under the foam they put in the box. It would not have built boost very quickly without it!

So yes there is a little round thing that goes in there. check the box really good if you haven't done so already.
