The relay for the switch on most models (I say most, as there are tons of models of Saturns and I have only come across about 10... but this meets all ten I've seen)... anyways the models I've seen all traced the switch back to the power supply and turned it on.
This means that the pin the chip is connected only puts out power when the system is on.
If you want to check for 100% sure slap a voltage sensor to the pin when the unit is off and see if its got any power.
