Here are the directions for replacement. Pic 2 correlates with the directions.

It may be blocked to see from the top by the transmission housing. Let us know if you have other questions.

That is what I would suggest. Note that it will be tight if you don't have it lifted. Keep in mind, the starter is on the left hand side rear of the engine, so the sensor is likely not visable from the top.
