C6 wiring diagrams or ground locations?
Anybody have any? If not, are there any common grounds that have issues on these cars? I have had a couple of odd glitches here and there and wanted to check/clean all the grounds and see if there are any common grounding issues with the C6 like the C5 has. I already cleaned the ones on the top of both frame rails behind the headlights. Any others? Thanks.

There are 7 total, as far as I can tell. One more near the battery, 2 in the "passenger area", and 2 more behind the rear axle. These are usually pretty trouble free, unlike the C-5s that had the multi-pin connector at each ground.

Thank you! I just want to give them a once over to rule them out. The two on top of the frame rails that I did clean were still painted over, they didn't even clean the stud down to bare metal before bolting the terminals down! There were a couple little spots of metal showing and that's it.

Do you know where the ones in the passenger area are? I want to check mine too.

I have a pdf that shows the ground locations and includes schematics. This was a dealer only pdf that came out at the introduction of the C6. I dont know if it would be of any interest nowdays but if someone knows how to send an 11 meg file and is interested....

Working in conjunction with that excellent ground map, use this to see exactly what is tied into those ground connections:

Um... I think I found 13? I pulled my info from a 2007 Helms.
2007 C6 Corvette Grounds
Ground points and what they control:
G101
G102
G104, G303, G108
G105, G107
G201
G202 1 of 2
G202 2 of 2
G301
G302, G401, G402
On 2nd thought, 12. One is for convertible OR one is for Coupe
Ok, we're good on 12. Pick the car type and you use a different G spot!

I know this is an old thread, but great info. Crabman, if you still have the mentioned PDF, I can walk you through sending it to me. Thank you.
