There is no standard "12v" connectors on the Lithium Ion battery in the front - it is a sealed unit: https://insideevs.com/news/546087/tesla-liion-12v-auxiliary-battery/
If you needed to jump it for any reason to boot the ECU there is basically a way to expose the positive cable and just ground to the chassy.
I'll have a look at mine at some point but don't think you're going to be running accessories directly off the battery anymore.
