Removing Electrical Connection

I'm going to change my engine air filter and follow the procedure in my owners manual, pages 10-21 through 10-22. I have a 2015 Z51.

Two questions, first does that procedure work?

Second, how to I 'remove' the electrical connection? I know this sounds really dumb but I have damaged plugs before when I pulled rather than pushed, pried rather than squeezed, etc. So how exactly does this connection come off of the sensor?

There is a small part that pulls out just a small amount. That releases the latch lock on the connector. Once the lock is released you need to squeeze the connector to release the cantilevered latch that holds the connector together. It can be tricky squeezing and pulling at the same time but if you place your fingers in the right position on the latch release squeezing with the right hand while pulling with the left hand the connector will come apart. I don't have a picture handy to show you the parts but if you look closely you see the part that is pulled partially out of the connector body. If I remember correctly it is a different color than the latch and the rest of the connector body.

Bill is right - disconnecting the electrical connection can be a bit tricky, but not too bad.

Thanks. I have a Z51 so I hope this is the same procedure. Also at 1:45 to 1:50 in the video he removed some screw and I could not tell what that was.

There are 2 screws on the top corners of the air box. There are tabs that secure the bottom of the box.

Update, the air filter change went very smooth. The video was great. I do have a few observations though.

When I loosened the torx screws on the top of the air box I was able to remove the front half of it without taking the entire airbox out. At around 1:15 on the video he has the entire air box out of the car. I didn't need to do that. He did mention that the new filter might be slightly larger (or something like that) so maybe he needed it completely out of the car to get the aftermarket re[placement in. Just speculating but I only had to take the front cover off and then the filter could be pulled out.

Second, I did find a small amount of oil in the air box front cover that I took off (see above) but NO oil on the filter. A concern? I do have a dry sump. So next question how long could that oil have been sitting there? I'm trying to determine which dealer did this assuming it is a concern. I bought the car with 8k miles on it and it had one oil change. The car now has about 29k miles and I have had the oil change done 3 times during my ownership.
