I need help with my Johnson 9.9

[Allen 79 wrangler]

I have been trying to install a CDI Electronics Power pack conversion part number 113-4488 on my 1989 Johnson 9.9 Serial number R08241545 Model TJ10ELCES. I am having difficulty getting the sensor to fit properly and could really use some instruction.

I do not see the sensor in the first picture.
