Some of you will get the title, some won't. I've got a friend coming over tomorrow with his 1969 VW Beetle. It has the most basic of electrical systems. He wants me to help him put in a hidden kill switch in it. Now that I've started to think about it, I'm at a loss as to what circuit to put it on. the first place anyone will look is the ignition wire, so I'd like to skip that. Plus this thing is so simple, it would be easy to supply the 12 v directly to the coil from a smaller battery that the thieves brought for just such an encounter. It's got a mechanical fuel pump. There is no clutch safety switch. I could put the disconnect on the line from the battery to the fuse block, but that would require a relay and also be kind of easy to figure out, since nothing electrical in the car would work. The ignition is really the only thing I can think of that I could put a switch on to keep it from being driven away. Am I right? And if so, does anyone have any good ideas for this purpose? Feel free to PM me if you don't want to put it up for everyone to read your good ideas, if word gets out about a certain hiding spot or trick, it kind of defeats the whole "hidden" part of HIdden Switch. I'm sure someone will have a good idea, so thanks in advance!
