hey everyone i was wondering if someone could give me an idea as to what parts of my wastegate have to go where. i have a tial mvs 38 wastegate i know what part bolts to the mani and which is the dump. but what do i need to send vaccum lines to it has 3 air holes in it and 2 threaded fittings on it. it came with plugs for the air holes i dont use and came with 2 air fittings that thread in. so where does each go and does the hole in the top go atmospheric? cause thats what i read somewhere. any help is appreciated thanks everyone
the top hole is so the plunger inside can move up and down when the wastgate open and closes, so that just vents to the air and the one on the bottom would be a vac source for your turbo. so a line from your turbo to the bottom hole on the wastgate and the other one i am gonna say just stays open as well...
heres a pic does this look right? the fittings i found i guess are for a new coolant option tial is doing do i need to use these if not do i have to block them?

This may help you if you havent looked at it already. Basicly if your not using a boost controler then you can just use a short peice of hose on the top port and vent to atmosphere. The bottom hose goes to your turbo as stated above, closer to the turbo the better. Most people tap there compressor housing and run a barbed fitting, then vac line from the turbo to the bottom port of your wastegate and your golden.

heres a pic is this right
i read that those two side fittings are for a coolant option can i just leave them and not use them? or do they need to be used or blocked off
Im have no idea about the cooling ports option. I have never seen that before. The top yes goes to atmosphere. The one you labeled BOV goes to a fitting that you taped on your turbo or charge pipe. Like i said above, closer to turbo the better. Most people tap there turbo compressor housing for that vac line. I just welded a bung on my charge pipe an inch or so from my turbo.
