Re: LSJ Cobalt/Ion Redline ECU pinout
 

Thanks for all those pictures, it is good to have those references.

I think this one should work.

If you can get the overall wiring diagram, including the pcm and fuse box, I should be able to locate a suitable terminal for the switch positive at the PCM. For now, it will have to do.

Re: LSJ Cobalt/Ion Redline ECU pinout
 

Here is the fuse block. The bottom left post is positive, and the bottom right is for jumping the car, as the battery is in the back.

The fuse block is right behind the PCM, so the positive would probably be better coming from the fuse block post.

Food for thought after this, is spray injection point.

Choice 2

I can get #1 for about $30 from a different vendor, and #2 is used for $50 or less. Been told that the meth doesn't affect the coating on the rotors.

Thanks for the fuse box picture. Do you have a diagram showing how the cables are routed and the functions of each. I need to pick one out that feeds the fuel injection system.

The bottom left is 12V and the right is connected to the starter motor?

Sandwich plates, both looks good. I suppose it doesn't matter where the jet is as it all points towards the center. I will get a better idea if they are in situ.

Scroll down to page 318ish for the SC version. I will try to find the wires coming into the fuse block.

Number two will mount the nozzle on the "top" of the intake manifold in the link

I could probably tap the right side for a second nozzle if needed.

Re: LSJ Cobalt/Ion Redline ECU pinout
 

I was hoping to find a similar diagram to the below, show where the power wires are terminated to the ECU and fuse box from the battery on.

Richard, i am going to send you a PM with information to get to the factory service manuals. It should get you everything you need.

Re: LSJ Cobalt/Ion Redline ECU pinout
 

Richard, looking at the drawing above, how is interrupting the bypass valve signal going to help lose boost if it fails open and allows full boost?

And as an edit, some of the other factory SC GMs have this same setup, so if we can get it working for the LSJ, it may be useful for the L67 and L32

Car is in the shop getting the MAP and Injector negative wire run to the steering column area. Will be trading a red gauge for a blue gauge.

Why shouldn't I install two systems? PPS up front and HFS-6 in the trunk.
