I just had my 2020's battery changed yesterday so I am very familiar with how all of that looks and is wired. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />The key is that there must be NO wires on the battery post where the disconnect switch goes except the disconnect wiring itself.BTW, everything on my 2020 worked fine after the battery change but disconnecting the battery does indeed turn AWD off. Also, my TPMS readings were gone but came back one at a time within a mile or so.I would not discard that short jumper or any connector because you may need to remove the disconnect when you sell the car and put everything back to original.</blockquote>
