Are you trying to remove the back half of the mirror, or the plastic cover over the IMPA on the windshield glass?

I had the same comment as NMMI82 based on your first question – that you do not need to remove the back of the mirror.

 

I am simply trying to determine if I have the camera KL3T-14H06-CE installed. If I have that, then I don't need to consider that part when collecting all of the parts I need to make ACC work on my 2019 F-150. The original poster states that you take off the back of the rear view mirror to tell if you have it or not. If there is another, easier way to determine that, that would be great; otherwise, I need to remove the back of the mirror as stated. Just don't know how to do that. Thanks for everyone's help.

 

You do not need to remove the back of the actual rear view mirror. You need to look for and remove the cover on the windshield glass.

Here is what the IMPA module looks like. It is about the size of 2 decks of playing cards and has a cover over it and is attached to the glass behind the mirror.

Do some google searching for F-150 IMPA module so you know what it looks like and where it is located.

What trim level is your truck?

 

I'll do the google search. I have a 2019 Lariat 501A package.

 

I did the google search and it took me to a similar forum. It said it was on top of the passenger side frame rail just behind the front bumper. When I look there, I only see radiator hoses etc. I do not see any electrical parts. I will keep looking...

 

Here is a photo from my truck. The big plastic cover on the glass. Behind the rear view mirror.

 

Oh, I see that. So do you just pull the cover off?

 

Yes, it has a few clips holding it to the IMPA bracket. I think I may have started at the top area and pulled down first, but I don't remember for sure.

 

This is what mine looks like.

 

You'll have to read back through this thread to find out if that is compatible. I would guess most likely not based on your package options but I'm not super familiar with 2019 parts.
