Can anybody post a wiring diagram or pinouts for the coil on plug (cop) on a 2008 cobalt? I need to know if they are ground switching 5v/12v trigger. I think they are ground switching because of the 1k ohm reading but I still need the pinouts. Any info about ms dwell and voltage required to trigger would help

Nobody? Did I post this in the wrong fourm section?

 

try that other place you may find your answer there.

 

Were you ever able to find out the information? I too am looking for the dwell values for the COP.
