I'm obviously not asking you to post specifics on how you did your car, but wondering what people are using these days for on-board anti-theft security (other than big dogs or big guns)? Getting ready to start wiring soon, so I figure it will be easier now than later... Fiberglass car, so I think the capacitance proximity approach is not an option. Also using old fashioned door & trunk handles, not electric poppers, which may also limit choices?
