For me to pass inspection at my local drag strip all cars need to have a working neutral saftey. So I dug through what I could find on the forum and learned about the mechanical function that keeps the car from starting in gear. My car was originally a colum shift. I found that most people splice into the purple ignition wire and run a wire to the aftermarket shifter for thier safety switch. I spliced into the purple wire ran the wire to the switch on my floor shifter and it still starts in every gear. What did I do wrong that this didn't work? I spliced into the purple wire right under the dash by the stwering column. I'm hoping someone can steer me in the right direction. Thank you for the help!!
