Security

If it a diesel put a relay and switch on the fuel cut off solenoid. if a petrol get a fuel cut off solenoid and do the same.

Put a switch in the main power to ignition harness
No turn on switch no power,itll never ever start
Any patrol fitted with an electric fuel pump, run a seperate switch for the pump, no turn on the pump/pumps itll get 50 metres at most

Its only kids and joy riders you wanna stop, the professional theif will know their way around any system
GPS tracker is good, but unless your on its tail of the mark,or within a few minutes,it can be either burnt or stripped in a few hours

I also found this thread that has been going for a while.
