In the old days you could just hotwire the clutch starter interrupt switch and install a simple remote start module. Highly unsafe if you forget to park it in neutral but that’s what people did (as me how I know)

Today due to countless reasons, besudes lawsuits and safety, the ECM not only looks for the clutch switch to be closed but also the brake pedal to start the car. And if you’re thinking “why not hot wire them both”, then your brake lights will be on all the time even with the car off.
