I'd rather avoid such delicate mechanical connectors if possible - maybe an 'address assign mode' jumper would be better - it wouldn't fail when using the car, because it wouldn't be there.
Couldn't we just use the ISP connector to set up the addresses?
Another possibility:
When programming the cell modules the primary controller unit IR diode is covered with something similar to a pen cap (or disabled by software) and another one is hooked up with a wire. The second IR diode works with much less current (let's say 2% of the current of the main diode) and is enclosed in a tube so that you can put this tube over any cell module's IR receiver and talk just to this one.
