Well, I'm not sure how that would work with your 12v system using the chassis as ground.Newfie_dan wrote:Simple theft deterrent is an electric fence kit wired to the body, touch the car poof nice little shock to smarten them up. You can set it for around 8000 volts or so enough to give them a nasty surprise. If that does not float your boat then install a battery disconnect for the negative terminal, use one that requires a key and hide it good so they are stumped when it will not turn over at all.
I've never got around to it, but I've always wanted to hide a kill switch. You can easilly wire one for the fuel pump, which would be a good one because it'll start for a bit than stall once the fuel lines are drained. Could do one for the spark system; easy for those who did the HEI mod. It's also how modern cars get disabled in their factory anti-theft system.
