The 1997 Dodge Ram 2500 doesn't have a separate "neutral switch" in the way some older vehicles might. The neutral safety switch (also called a neutral start switch) is integrated into the transmission itself. It's not something you can easily access or see without removing the transmission or at least part of it. Its function is to prevent the engine from starting unless the transmission is in park or neutral.
If you're having starting issues, the problem likely lies *with* the neutral safety switch, but it's not a simple switch you can replace by finding it on a dashboard or under the hood. A mechanic will need to diagnose the problem. They may test the switch's wiring or even the switch itself, potentially replacing the whole unit within the transmission.
