Picked one up was a three prong plug all in a row can not find one on the transmission like it.

 

It should be on the driver side, just above the pan. Did you get the right part? Rockauto shows 3 styles.

This. Even GOOD parts stores are at the mercy of their databases, which sometimes have errors. I just got a wrong part for another vehicle from NAPA, and my local NAPA folks know their stuff. If it doesn't fit, don't assume your car is wrong.

 

That's the right switch. It should be near the shift cable entry. The ball rides on the shift quadrant inside the transmission and the three pins are neutral safety, reverse lights, and power. The plug will only go it one way. The wires are very susceptible to damage and corrosion from road debris. My reverse lights quit working because one wire had rotted off at the plug. A new plug is available at a dealer.
