Well at least they were smart enough to pick the fastest one...

 

If you are worried about it being stolen, LoJack is a good option.

Last time we bought a system it was $500.00.

Almost every vehicle in every department has a receiver including aero.

An armored pull cable on the shutdown lever with a keylock ****.

You could secure the side of the injection pump from tampering with a removable welded cover.

 

here is a very simple idea, idk if it will work on your trunk, mine is a 5 speed, but years ago my neutral safety switch went out of adjustment so i wrapped a peice of wire around it so i could pull on it when i wanted to start. It was ment to be a temporary thing but i found it kept others from moving my truck on the job site so i left it, been that way for maybe 20 years now. nobody can start my truck cause they dont know how
