After a long winter, finally got it started last night. It’s currently running on the stock ECU, I have the ecmlink v3 that’s going in this weekend. After installing the new intercooler piping, boost gauges, boost controller, bov, I’m getting a little lost in where all of the vacuum lines need to go. Anybody have a diagram that shows the mapping of everything?

2G - Where does this vacuum lines go to? And EGT sensor place (close it)

Hi! I remember removing 2 vacuum lines at the waste gate solenoid because I wanted to remove the restrictions but I don’t remember if the vacuum line that I have marked is gonna go under the second line where the restriction was? And On the Manifold where the EGT sensor is, can i Plug it with a...

2G - 97 GST Vacuum Hose diagram

I was wondering if anyone has seen a hose/vacuum line diagram for the engine bay much like the wiring diagram that they have for the harness?

Thanks for the links!!!

No problem at all! Don't forget with the V3 you can turn off the engine looking for Emissions stuff which means you can potentially delete it all which also gets rid of most of the vacuum stuff.

Definitely still researching the ins and outs of the V3, seems like it's never ending of the options.

I was mainly looking for routing of aftermarket add ones and how folks have them on their car. I have an inlet on the new intercooler piping, where would that go? I currently have the BOV and FPR going into the intake so now I need to do the intercooler, turbo, waste gate and line from the gauge

I'm definitely not an expert, I'm kinda of just learning as I'm going with my own car but from my research it seemed like the IC inlet could be used for a BCS (though they don't recommend since they recommend a port right off the turbo for this reading). What I found in my reading is it is typically used for BOVs that have a vacuum source on both the top and bottom of the valve. My BOV bottom vacuum line runs to the IC port. However, I don't think this is needed.

1 step forward and 2 steps back. While trying to figure out a misfire, we replaced plug wires, coils, ptu, CAS, and throttle position sensor. Now we're at crank no start, have power to CAS, PTU, but no spark. I've also never heard the fuel pump prime before starting it, I can manually turn it on thru the ECM. The FPR shows 43.5 on the gauge while cranking. I checked the MPI relay and I'm pretty sure I hear/feel it click when the key is in the on position. Any thoughts or ideas on where to look next?

As a safety feature on these cars the fuel pump only works when the car is cranking. There is a tester plug on the wiring harness towards the upper back part of the fire wall that if you run power to it will kick the fuel pump on. Just make sure you do this with the correct one since the blue plug is not for fuel pump, that is to check rpm's (I learned the hard way). If the pump is turning on with ecm link then your probably fine there.

Are you running low z or high z injectors? If high z, did you get the adapter for the resistor pack?

Other than that, I am going to let more knowledgeable people help you out with this more.
