Broadcast Code is a way to track various proms released by GM. 
Boadcast codes (like AXSH 2423) can be used to find the vehicle,
emissions type, engine size that a calibration was installed in.  It's
more commonly used to see if the latest release prom is installed in
the car.

How about just the pinouts?  They look like these:

I would put the ZR1 pinouts up for comparison by all.
