Recently I began making minor modifications to my interior to learn more about the breakdown and wiring of my 1998 Toyota Camry V4. My latest idea is to create a push button ignition that requires the key to be in the ON position (for security). Upon inspecting my Haynes repair manual I discovered the following:
- The ON switch position contains two continuity circuits: (2-3-4) and (6-7)
- The START switch position contains two continuity circuits: (1-2-4) and (6-7-8)
which led me to the following conclusions, of which I am not at all certain:
- Installing a pushbutton that activated the START circuits while having the key in the ON position would activate (1-2-3-4) and (6-7-8) which could overload my car
- A pushbutton should therefore OPEN the 3 wire from the ON switch while simultaneously CLOSING the 2 and 8 wire
I think this can be accomplished by using Normally Open and Normally Closed control blocks in conjunction with a momentary action button. However, I have never worked with electronics before and am hesitant to proceed without any advice. I know there is a packaged push button system available from JCWhitney, but that would defeat the point of trying to learn how all of this works. If anyone has ever attempted anything like this I would appreciate any tips you have to offer.
