You can buy 9 volt battery gizmos that plug into your power port to retain your ECU (and radio) settings when you swap out your car battery. Maybe that's one reason why they run the data interface that way.

Excellent point Steve. I have seen the dealers insert a plug into the cigerette lighter with a battery on the other end when swapping out 12 volt batteries. Was told it keeps the memory in the computer while the 12v battery is disconnected.
