- Top picture ............ ecotec product (from link)
- Bottom picture .......... googled. It has three port.

I think they are the same valve. One with dust guard

Can you tell me where the ports is connected to:
a ...... assume to atmosphere?
b ...... ?
c ...... ?

Re: LSJ Cobalt/Ion Redline ECU pinout
 
C is atmosphere, hence the dust guard in first pic
A connects to the intake manifold and B connects to the bottom port of the "SC bypass actuator". The electric connection on "A" side faces the back of the car. The coworker that was supposed to help me with the car took off before lunch so it will be after work before I can tell you the connections, although from the pic it seems like there is only two.

I think I have enough information to produce a wiring diagram for your car. Give me a few day.

If available, can your source a ECU wiring diagram and a picture of the PCM (pin out side)? You have already provided the pin out.

Almost the same, but the high speed from 1 and 2 aren't there for the Redline from what I am reading. Here is the Redline pinout

Please check the diagram below is correct.

Re: LSJ Cobalt/Ion Redline ECU pinout
 
I have all those diagrams already. I like to see the wiring outside the PCM and may be an image of the PCM itself.

Re: LSJ Cobalt/Ion Redline ECU pinout
 
Is this the correct PCM?

That looks like it.

Between the fuse box and BOV. LSJ, but turboed. Leaves more space in that area to see it.

This is the next generation of the engine, but it has a much better pic of the PCM.

Look in the middle of this picture at the blue piece. That is the elctric connection for the solenoid above.

And should your first 29 in the diagram you made be 33?

Re: LSJ Cobalt/Ion Redline ECU pinout
 
Sorry, made the correction. I will make the H4/LSJ wiring drawing as soon as I can.
