Does any one have a drawing of where all the ground locations are located on a 2001 Camaro LS1? I'm still having Electrical Problems with my car. Just picked it up from the dealer ship and they still did not fix my problem. I would like to check all the grounds myself. So far the dealer changed alternator battery cables. Changed the RPMs at IDLE. But it still is having issues with the car is at idle or park running. Voltage gauge jumps all over the place and light flickering. Seems to happen when the car get hot.

 

im having a similair issue, idle kinda low.. bogging down a bit, voltage meter jumpin everywhere lights flickering... i have found a ground wire hangin down below the motor.. seems like one end is grounded on the block.. i cant find out where the other end needs to be though... help us out someone :\ lights flickin bugs the **** outta me

 

Hope I'm not too late. I compiled this list myself from the Helm manual for my own use. It is as accurate as I can understand so it may contain some errors. If anyone finds any errors, please feel free to correct them.
