Okay so i once was in the web searching how to hook up my 3 port and so forth, so here we go for future use!!

3 port solenoid


As for the wiring one wire goes to ign switch 12v and the other to ecu.

4 port solenoid


Wiring same as above.

And also if turbo doesnt have a vacuum fitting, then you will have to get a source off the Intake manifold to supply the vacuum to the solenoid.

And as a added bonus ill throw in MBC diagram for internally gated and external gates






Happy Boosting!!
