This is located on top of the transaxle, and I have attached location views below.
However, the easiest way to test this is to go to the starter and check voltage on the trigger wire.
If there is no voltage when cranking the engine, then go to the starter relay and jump the relay. If the engine still does not crank, then the switch has failed.

The info on how to complete this is attached below. Please run through this info and let us know what questions you have.
I also attached the process on how to adjust it in case you need to do this as well.
Thanks
