Re: CarDefender security system? Anyone?
If you don't want an alarm, there are plenty of ways to secure; i.e., prevent the car from starting easy for $10 in parts.
A heavy SPST relay in series with the neutral safety circuit, coil supply, etc.
The energizing coil on the relay could be triggered by a momentary pushbutton hidden, or two pushbuttons in series in different locations hidden, by a radio pushbutton, turnsignal lever, fan switch, the possibilities are endless. It would slow a pro thief down a bit.
I installed an alarm myself, b/c I wanted auto door locks, trunk pop and I have an empty channel on the remote that I will wire to my RS light motors for grins.
Whatever direction you take I recommend sticking with the starter circuit. The coil or fuel pump could leave you in a bad situation if it wacked out at 70 mph, or at another critical time.
