Flyzeye Interior Lighting

Bump! crossposting here as I am looking for any assistance from others who have installed the wired V2 unit.
I'm looking for help on install; the instructions mention making the indention cut into the plastic. I was wondering is that on the surface of the mounting dash kit or is that part of the OEM plastic that I just cant' see for some reason ? it's hard for me to see if I have something else b/c my dash kit seems to be taking up a good portion of the bottom surface. I have the Scosche kit and god it has such a drastic lower lip with sharp edge I took off my HVAC controls and couldn't really tell where i'd be cutting into. It goes in mounted already with the side brackets to the head unit so I can't take it off by itself like u can with the metra one. i'd attempt changing it but gosh i've had awful luck getting those wires back behind it again and wouldn't wanna mess up the install job. Here’s the best pics I can really offer since I can’t remove the face plate as it’s attached to brackets to the head unit. It’s the Scosche Double din kit for 2005-2011 Tacoma’s. Here’s a pic of it stock and the best angle I can get after taking my hvac cover piece off. I guess my question is what plastic i am supposed to cut. the plastic of this dash kit undersurface ? Bc I don’t really see what else there is to cut. And how far back into it to cut? Sorry I’m new to mods and trying my best but need like the best description possible and want to do this the right way. Thanks in advance so much guys! pics below to help illustrate the best I can. -I know it's challenging to try and talk through it without being there
