MAF ground location.
 

I’ve got a 10 SS that the maf will not read on. It’s losing ground. Voltage will bounce between 6 and 11 volts and if you hold the harness just right you get 12.15. Key on engine off. I’ve replaced all eyelets on the passenger side with no luck but I’m not sure where that ground actually goes when it leaves the maf connector? Anybody know? I’m about to just run my own ground straight off the maf and be done with it.
