Would it be wise to put a cut off switch hidden somewhere in my classic mustang?
just started doing the wiring on my 66 mustang and looking at it, it looks like it would be easy to hot wire, very basic system! would it be wise to put a hidden switch somewhere that you had to flick before turning on the ignition. just wondering if anyone has had a problem or is it works for them. or if this is a stupid idea. cheers and thanks for your answers
I wired a lot of oldies in my days, but back then they were still under warranty. The primitive anti theft system I came up with back then was to use 3 single pole, double throw toggle switches. These are the ones with 3 blades in the back. Depending on the position of the toggle, the centre blade is connected to either the top or bottom blade. Run the coil feed wire, ( hot, ignition on) to the centre of the of the first switch. From which ever blade you chose as the coded one, run a wire from it to the centre of the second switch. The same procedure applies to connect switch 3.The last connection is to connect the wire leading to the coil on the back of #3.The combinations are numerous. UUU, UUD, UDD, UDU, DDD, DUU, etc,. Now the anti theft part. The unused blades at the back of each switch are wired in series and continued down to the horn side of the horn relay. If there is power applied to the coil from the ignition switch or a hot wire at the coil, the power will flow from the ignition wire directly to the horn if any of the 3 switches are in the wrong position.
