LSJ Cobalt/Ion Redline ECU pinout

According to the poster, when the solenoid is unplugged, the boost goes up. This is not good. He was a bit vague about what eas unplugged, a hose of electrical connector?

He wrote:

Watch how your boost climbs. When I unplugged one of my connections or lines to the solenoid (dont remember whcih one it was) when I was testing if it was bad, the boost would go to about 10 lbs and then ramp up to 20 within about a second or so when I went WOT. It felt like a car with a small turbo. Also since our cars are not boost referenced for fuel delivery it would go to 10:1 on the wideband for that second or so. Its worth a check

Can you make a bit more sense from above?

Do you have the S/C system on your car at the moment?
