I just replaced my 07 G6 2.4L starter and the car turns on perfectly. Except now, the transmission is acting all goofy and spitting out about a dozen or so errors. I go back to fix the grounding, only to find that when I try a different combination, the car doesn't even attempt to start again. Does anybody have a diagram/ explanation on how to ensure I have my grounding correct? Thanks! (Yes, I've looked at youtube videos but I have not found one either explaning the hookup or it's a different starter.
