Install help.

So I’m installing the 2.9l gen 4 and I’m trying to figure out where the hoses on for the boost actuator go? I’ve got everything on the car and now I can’t figure out where the line goes.

Are you running a crusher set up? I'm running a standard inlet and used the stock lines to hook everything up to the back.

 

[esonu]

Standard. I don’t even see any connections available to hook it up to.

I have a Gen 3 but the bypass actuator hose came pre-installed, connected to a fitting down near the IAT2 sensor. If your actuator has 2 hoses, the second one can remain open to atmosphere.

The fitting on the lower right is for items that need vacuum and boost reference such as the FRPS and boost gauge. The 3 fittings on the upper right supply manifold vacuum for EVAP, boost dump solenoid, EGR, etc.

That’s exactly what mine looks like. So the two hoses that are supposed to connect to it from factory are just supposed to be left open?

Just as a reference I’m referring to these two lines

At the very least you need to cap them. I pulled them out of the elbow completely and plugged the holes in it

Sounds good. Just going to plug the lines. Now the next problem showed up and a fuel rail bolt broke. Problem after problem on this build.

Sorry I misunderstood what you were asking in the first post. As stated you can just plug the lines or you can remove them and the boost dump valve and have your tuner turn it off in the tune so you don't get a CEL.
