Thank You so much for the detailed guide. Highly appreciate you taking the time to post.Sorry, this took awhile due to snow.
F150 Gen 14 Mirror Assembly
Replace Cap Bing Videos
There is a slot behind the glass to insert a longer screwdriver from the bottom outside corner and twist the screwdriver to pop the glass off.

Fig 1.
This shows the guides to get the screwdriver into the slot to twist. First time is a little rough because it sounds bad coming off.
Following the above video, remove the glass and the cap. Be careful of the wires (BLIS is very small and can be pulled out of the plug).

The plug needs to clear these prongs to come off of the mirror, the tab at the top of the picture is where the wire hooks into.

This gasket (?) comes off just be careful not to rip it.
You should only have to disassemble anything that prevents removing the wiring harness on either mirror.
However, you may have to take the piece off in Fig 4. Be careful of the long tab because it will break off easily. The one in the picture is broken.

If the new mirror assembly has all options except the power fold (as in the XLT – Not sure if the XLT has position sensors for memory see Fig 5 and check for the sensor wires), I would take the harness out of the XLT version and add the wiring for the fold motor if everything is populated except for the power fold wires. If they are not there you will have to run the coax to continue to have memory mirrors. The coax will be difficult to retrofit unless you don’t care about the grommet in Fig 6. You should be able to take this wiring off of the power fold harness (Lariat) including depinning at the connector (Fig 6. Exterior Mirror connector C521/C622 Blue).

Fig 6 Red shows Power fold connector and thread them through the grommet (Fig 6 Yellow).

Depinning and adding to the connector (Fig 6. Blue) should be covered in other postings. Each connector can differ.
The most difficult part of removing/replacing the wiring harness is routing all of the connectors through the hinge hole but everything will fit if you bring one connector through at a time. The plug for the power fold goes right below the yellow circle (Fig 7. Red).

Once you have added the wiring for the power fold, reinstall the wiring harness. Wiring goes out of the hinge hole (Fig 8. Red) and loops through the hook circled in yellow, then off to each component.

Ensure everything is plugged in, all connectors are unique so no issues with what goes where.
The grommet goes in the hole in Fig 9 underneath the gasket.

Install the caps with ones that support the camera/puddle light plastic component. Reinstall the glass.
Let me know if you have any questions.
This will be a big help.
I am not sure if the XLT mirrors have the dimming feature as well.
What I am thinking is just move the camera (along with housing) and back cover from the XLT and put these into Lariat mirrors. Provided thats achievable.
Most probably will have to cut the white grommet.
It's snow and too cold here as well, plus my parts are still coming in, will update you when I start with this.
