why do you have a switch that kills power to the PCM? is this so your vehicle doesn't get stolen?

no i won't see it hurting it, just everytime you do that your car will have to "re-learn" the fuel trims and such

All of your internal emissions tests for ODBII testing will be continually reset and will fail you for too many incompletes if you have OBDII emissions testing in your state/county.
