Hi Dan,

If you look inside the opening at the top of the plastic piece, you will see the two small resistors that make up the MAF sensor. I wasn't able to see them without a flashlight. I ended up using my camping head lamp (aimed straight down) so I could see the wires while spraying them clean. Remember these things are tiny and they look exactly like the picture in the article. You'll know when you see them. Good luck,

Nico
