Morning all to take the pcm unit out,  is it park it in Drive then just disconnect battery, if it's in drive I can't take the key out even though the screen says remove key from ignition.   I guess no harm disconnecting the battery like this

I didn’t disconnect the battery when removing PCM for the Joyeauto upgrade but can’t see any harm in disconnecting and leaving key in. Make sure you don’t close the frunk! Worth tying a small cloth around the latch on the frunk to prevent accidental closing.
