Hey Michael,
Here's the wiring info. Just make sure your factory wires match up.
I don't have my original square nob. I wish I had kept it but I moved a few times and small things like that tend to get lost or thrown out when that happens. I believe the old nob will fit the new switch but I don't know for sure. I may have the knob 3D printed if I can get a hold of a scan of the original.
