7. Drill the hole for the fitting. Be sure to drill a straight as possible. WEAR SAFETY GLASSES the air will blow the shavings out.

8. Tap the hole. WEAR SAFETY GLASSES the air will blow the chips out.

Tip.. if you dip your drill bit and tap in grease. The Grease will collect the chips and shaving while drilling and using the tap. Allso slow down the speed a bit to let the grease do its job of collecting the chips/shavings.
Clean and reapply fresh grease to the drill bit / Tap if it gets loaded up.
I have and others have used this, it works well..

I used the sensor on the driver front head for the PCM, but my car doesn't have a guage(too old). I put the mechanical guage in so I have a guage.
