Greddy knockoff BOV questions
I picked up one of the purple topped Greddy style bovs on ebay. Same exact https://www.miataturbo.net/forum/sho...ght=greddy+bov
And, I have a few questions: It did not come with intructions, so what are the functions of the two vac nipples on the back of it? I know it needs vaccuum signal, but I expected there to only by one nipple, and the two nipples are not the same diameter - the bottom one is the normal diameter for vac lines and the top one is larger. What do I connect these to for it to work properly?
Second question - I also purchased a weld-in flange for the bov, and welded that into my intake piping just before the TB. But my problem is in finding a fitting to put into the intake piping pre-turbo that is large enough in diameter to fit in a tube coming from the bov - the bov's outlet tube is like an inch in diameter. Too large for something like a brass hose barb that I could drill and tap into the intake tube. Any suggestions?
Thanks

Top one gets vac source from after TB, so off of the Intake.
Bottom one is optional, but by putting it PRE TB, you will find it responds a hair faster.
So TOP = after TB vac source
Bottom = PRE TB vac source (optional)
Take a picture of yours and show the fittings, I'm curious about the size variation. Typically they are identical sizes.
