Hey

Best thing is have a good insurance policy. If they want your car, they will get your car. Even if you deter them the end result will likely just being tons of damage since you're already dealing with upstanding people.
Hide some airtags/smart tags in the car.

Hey
Yeh it's stock 20amp mini fuse
I Bought a piggyback fuse tap holder with 20amp fuse like in the picture,
12awg wire,
Rocker switch
also another 20 amp fuse holder
Just checking thats how I would wire the piggyback fuse tap also??
Also it won't cause any issues electrically??

There’s no positive and negative here, just a path for current to pass through (to the circuit it looks like a wire).
If the left most fuse contacts (in the picture) are both connected to the left tap tab, and right most fuse contacts are not connected together internally, and the right most bottom fuse contact is connected to the right most tap tab, you should be good to go. Use an ohm meter to verify the internal connections of the tap.

Ok cool
So pretty much how it is in the picture will work fine
My diagram is was just gonna add another 20amp fuse in the circuit for safety
