Where is the backup neutral safety switch located on a 2002 dodge Dakota V8 4.7?

The 2002 Dodge Dakota V8 4.7 doesn't have a separate backup neutral safety switch like some older vehicles. The neutral safety switch function is integrated into the transmission range sensor (TRS), often also called the neutral safety switch, or sometimes a PRNDL switch. It's located on the transmission itself.

To be more specific, you'll find it on the side of the transmission, usually near where the shift linkage connects. You'll likely need to access it from underneath the vehicle. It's a relatively small electrical component with multiple wires connected. A repair manual specific to your year and model will show the exact location and provide diagrams to aid in identification and replacement.

Keep in mind accessing it might require removing some other components, so you should consult a repair manual for detailed instructions.
