It took some force to get it out.
The mirror remained intact.
During the process it didn't feel like it was going to break.
I adjusted the mirror all the way to one side and then I reached in and pulled the mirror.
Take a look at the tabs I circled in the photo.
That's where the mirror is...
I did a very similar install but used the Nilight 8PCS Truck Pickup Bed Light Kit 24LED White.
For a clean install, I used the rocker switch from Maverick Innovation on Etsy.
I would pop the mirror off on the original to see if it matches the eBay pictures.
I have a 2026 XL with BLIS and I had to replace the entire driver side assembly.
Here is a picture of what mine looks like.
