I have one on my truck because I wanted to eliminate the pedal and all the attached cable nonsense. Works great, I didn't install it for theft prevention but it certainly helps. I also have an electric fuel pump kill switch. With EFI, it ain't starting without the pump on.
But most importantly, I have a hidden commercial GPS tracker that are normally used on semi truck trailers. It is powered by 4 AA batteries that last 10 years and operates on 5G. If the worst happens and my truck gets dragged onto a flatbed, I want to know where to go find it!
