you can relocate the factory deck but it will not generate the RAP or accesory for you. those features are controlled by class 2 data which means your aftermarket deck can't use the information that the stock deck uses to turn on or stay on till the door is closed. You will have to use accesory from somewhere else, and the ignition harness is no use cause it's low current and low voltage not enough to run a deck not to mention that the passlock and ignition share the same wire. YOu will need to use a relay. I highly suggest you take it to a certified installer.
