There should be a flat spot to drill and tap on the compressor outlet. 1/8 NPT.

You can put it any place on the boost pipes too.

There's the big square lug but that's all I see. Where does it need to be drilled?

I drilled and tapped it today. After having the compressor housing off and looking at it I'm going to have to either polish or coat it! Winter project for sure!

its interesting how there are several ways to setup the wastegate to boost controller. ive read before to connect how was mentioned in this thread, while i have it different. My bottom port from wastegate goes to turbo outlet and its "t'eed" to boost controller, then from boost controller back to top wastegate port. Like this, I raise boost when i turn **** to the right....and less boost to the left.

This is a "two-port" method which uses controlled boost pressure to hold the wastegate shut in high backpressure setups. "One-port" uses boost pressure to open the wastegate, hence the opposite behavior with the controller. I think I have that right.
