Can anyone get wire diagrams for the neutral safety switch for 99-02 4l60e please

No direct neutral switch. It's all in the big rectangular connector. Here you go. This is for an 06, wire colors may be different (but I doubt it) pins will be the same.

My ns switch is the other style with 2 plugs

Ok. The 4l60e has 2 big plugs, the one I showed you above. And this one. And clearly it has nothing to do with the neutral/park switch. Then you have the VSS. That's all there is externally.


And here's the complete wiring diagrams for the 4l60e.
