Does anyone have the pinout for the ECM for a 2009 HHR SS with the automatic transmission.

I am specifically looking for the locations of the 3 wires for the ckp crank position sensor.

Thanks for any help

I don't think they are different. But it is the 96 pin conn.

Looking at the chart it looks like the purple and and light green wires from the crank position sensor must be pin 45 and 46. They were the only purple and light green wires that did not have a specific description.
