Bringing thread back from the dead as I am in the middle of doing the same thing. I purchased a 2015 Limited Visor for my 2017 Latitude. Same issue, plug it in, vanity works, homelink lights are not on when pressing the buttons. Looking at the two visors my original one had two pins and the new one has three. This got me thinking that additional pin must be Vin to HL circuit. Looking at harness form headliner I see three wires - yellow/orange, black and gray (from right to left). Black is obviously ground and yellow is connected on old visor. Measured the voltage across yellow/orange and black I read 12V, do the same across gray and black and read 0. My guess is Jeep leaves the wiring together and there is a setting to cut off power or not, depending on the package you purchased. Tonight I will jump yellow/orange wire to the new pin on new visor and report back. If that works, I will probably put and inline tap on yellow/orange one end. Cut grey and solder jumper to that line.
Let me know if anyone else has completed this swap yet.
