So I am about to put my turbo on, and i just noticed something. If I wanted my boost WG controlled, i would run a vacuum line from the WG nipple to a nipple off of the turbo, correct? Well I just noticed that my turbo does not have a nipple on the turbo, so does this mean i will have to purchase a boost controller to control boost that way?
I have tried searching, but Im not having much luck, only seeing stuff on the big 16g turbos.

You don't need vac signal for a wastegate, only boost, so it does not need to come from the intake mani.
Drill and tap a hole in the compressor housing for a nipple near the outlet, or do the same in the intercooler pipe just past the comp housing as suggested above. I ran my big 16g this way. You can either go straight to the wg actuator from the new nipple, or through a ball/spring type boost controller on the way. On my Evo3 16g there is a blind drilled boss about an inch from the outlet that's perfect for a boost source, you may have the same thing on yours.

As stated, yes. This will give you wastegate pressure only. Just be sure the nipple is completely sealed, and won't pop out under pressure. Best way is to weld on a bung and thread the nipple in. Ghetto way is drill a slightly undersized hole and 'screw' in the nipple with some JB Weld to seal it.

Okay guys thanks, just making sure what i have read was correct, Ive never boosted a car before, Just owned a car that came boosted, So its a little different when you actually have to do everything your self. Also For the BOV, that needs to be teed in BEFORE the throttle botty, correct?

For the BOV I wouldn't tee into anything so you get a good vacuum source to make sure the valve operates properly and to prevent compressor surge. If you don't have cruise control I'd just use the nipple on the IM for it. Otherwise if you have to tee off one or the other, I'm not sure it would really matter.
