Does anyone know if it's possible to install a proximity alarm to prevent someone from stealing gas by drilling the gas tank that is compatable with the oem theft system on the truck or have it work by itself? Does it exist?
I once had an aftermarket alarm (Alpine) on a vehicle with the proximity sensor. It would detect any movement within 2 feet of the vehicle and emit warning beeps. If movement continued it went into full alarm. I would imagine there is still something like that available.
