The neutral safety switch on a 1986 Dodge Ram Van with a 318 engine is located on the
transmission. More specifically, it's typically on the
passenger side of the transmission, near where the linkage connects to the transmission. It's a small switch, often cylindrical in shape, and is part of the linkage mechanism that prevents the engine from starting unless the transmission is in Park or Neutral.
Because of the age of the vehicle and potential variations depending on the specific transmission type (e.g., 727, 904), the exact location might vary slightly. You may need to consult a repair manual specific to your van's year, make, model, and transmission type for the most precise location. A picture diagram from a repair manual would be extremely helpful.
