2001 Impala Won't Start....Future FIRE?!

The door locks have at least three components that ground at G202, the radio grounds at G202, annnnnnd (drum roll please) the fuel pump relay grounds at G202.
They only identify the grounds by number, no locations are given. They use the same numbers as the FSM. The dealership should be able to give him the location and I do mean give. If they knew about the locks & radio they should be ashamed & actually give him a refund.
G202 is located on the lower center left side of the instrument panel. Should be near the Data Link Connector, just a bit lower and slightly to the left against the firewall.
Hope that helps.

K I have an update:
After speaking to good ol' Ron at the dealer, he suggests the BCM because I found out today that yesterday in the shop they pulled a code that pointed to the BCM in some way. Not sure exactly what it was, they didn't say. Ron has seen these go bad and its something he has replaced on various 2000+ GM'*. This is a weak lead, but its something. He is ordering the part and I get to decide if I want to do this next Friday when I don't have classes.
Intesting find about the grounding to the radio though. I'm very new to this W-body and its interior, so what is the best way at getting to this "G202"?
The Bonneville interiors I could have torn apart in a matter of minutes, but now I'm a scared pup. :?

You'll be looking for a some type of electrical connector that has black & black with white stripe wires going to it. Here'* a link to a Techinfo article showing bus connectors on a Bonneville.
