Default 07 Mustang v6 convertible Ground locations 6 dashes for odometer. No start!

Does anybody know or have a post where the factory grounds locations are in the car? My odometer shows correct mileage for a second then shows 6 dashes and won't start. I hear that is probably a ground issue. Any ideas?

Ok problem solved. I pulled the power distribution box to check visually and meter all fuses. My thoughts were that there's no problem in double checking. All fuses passed. I then moved onto relays to complete the process. I found a failure at 20 relay which is for the pcm. Rust. G damit. So, odometer going from correct to 6 dashes means pcm miscommunications.
