After inspecting the wiring harness diagrams in the service manual, the camera cord is wrapped with the Antenna harness.
This is the part list I have for adding the OEM smart rearview camera to a '23/'24 Ascent that already has the Auto-dimming Homelink mirror :

94310XC01AVH | $64.00 | $44.54 | Liftgate trim cover for rear camera of smart rearview mirror |
909130105 | $1.36 | | Body D Pillar Trim Panel Clip. Door Interior Trim Panel Retainer. |

Challenges:
1) The OEM Smartview Mirror needs a CANBUS connection per the wiring diagram. The connection for the existing chromatic mirror is physically the same, but may or may not have those pins active. If not, then there are more wire harnesses at the front of the car that need to be replaced.
2) The difference between the antenna harness part numbers (86325XC65A and 86325XC66A) is unclear, they show up under the same listing but have different prices.
3) Not sure the difference between the mirror part numbers either (86374XC00A, 86374XC00B) but these cost exactly the same, so probably inconsequential.
4) Removal of the roof trim to add the wiring requires taking apart a significant amount of the pillar trim as well, not all of it uses clips so there may be some adhesives that need to be replaced.
I am interested in trying this out but reluctant to spend ~$700 on the rear-view camera to find out the CANBUS pins are not active in the existing wiring harness. If I can find the mirror cheap on eBay or from a wreck, I'll give it a shot.
