The neutral safety switch on a 1995 Chevy van is located on the
transmission. Its exact position varies slightly depending on the specific transmission (automatic or manual, and the type of automatic) but it's generally found on the
side of the transmission case near the linkage that connects the shifter to the transmission.
You'll likely need to get under the van to see it clearly. It's a relatively small switch, often with a connector attached. A repair manual specific to your van's year, model, and transmission type will be the best resource for the precise location and visual identification.
