Ben,

Unfortunately,  the Motronic world has been held hostage by the few with 
the knowledge.  Recently more details are becoming available to the 
public thanks to the work of a few.  Spend some time reading on these 
sites...

The people on these sites are considered 'thieves' and 'pirates' by the 
ones with the knowledge.  Funny, eh?
You're somewhat lucky to be playing with a 93,  the older they are the 
simpler the design.  The newer ones have tentacles throughout the 
vehicle and are much harder to reverse engineer or replace with 
aftermarket.

hth,

Bill
