Hi Chazalby,
You can see it on the bottom left picture. It goes into a plastic elbow on the intake tube that feeds the Provent catchcan. It should work if you connect it anywhere between the MAF and turbo where the intake pressure is the lowest.
I had it adjusted to deliver about 1 drop every 5 or so seconds at idle. The higher the air velicity, the more petrol would be consumed. I only ran this system for a couple of months as it turned the oil very dirty black after a short time and after a few oil changes the oil remained fairly clean, so I removed it. Also, eventually the dripper container did perish from the petrol, so another reason to remove it, but it did the job.
Cheers,
