Okay, it took looking in 5 boxes, but I found it.
Pictures are attached. It's a blue samco inlet hose. One of the ports it blocked off because I was using a catch can that T'd into a single inlet, and since it's siliconed and hose clamped in there, I didn't pull the plug out out. If you want to run it with all the OEM hoses attached, I think it's just a matter of pulling out the plug.
Also the turbo side of things is a bit chewed up as the person that installed it on my GT30-10 had to stretch it to get it to fit and over-tightened the hose clamp.

But that shouldn't keep it from working just fine.
I paid like $300 for it, I'll sell it for how about $75?
