Making a car difficult to steal

If you "did it right" it would!!!!!!

So is my wiring diagram "did it right"?

Check out I believe Moroso is using an improved 4 terminal disconnect switch that is with improved ratings

I would prefer to avoid a disconnect if possible. Really would prefer to be able to just get in the car and start it with a minimal amount of fiddling around. Really don't want to go into the trunk. Disconnect would be more for additional safety when in storage or something, not for around town, if at all.
