Part ordered. I’ll try it out this weekend.
Parts arrived and after looking at that new wiring harness, it's, unfortunately, not what's needed. This is a HVAC harness, but I suspect the harness that connects the sun sensor, cabin temperature and C2 on the HVAC module is part of the 'Body' Wiring harness, rather than part of the HVAC harness. The trial failed...the part is being returned. We're now stuck...

Interesting....wonder how to confirm. A few of the discontinued variants (i.e. 68413040AD can be purchased for ~$125). It may be worth a trial...

Just keep in mind there are more than 10 different part numbers for it depending on the options and 125 is really cheap.
Edit: Looking at sales codes it should have correct plugs. Really tempting as I need it to add heated seats and steering wheel.

i apologize upfront for the dumb question. I have a 2019 JLU Sport with the 5" radio. I bought a 7" radio and the climate control unit. My Jeep has the sun sensor already. Does this need to be replaced with the new one that came with my unit?? Also the in cabin temp control piece would I have that already if I have the sport?? I purchased mine from Infotainment and it came with the sensors. Their support team told me I would not have to replace these two sensors and it should work properly. Im not too sure I am getting the right info. Im just trying to figure out exactly where to find the harness that I connect the in cabin sensor to. Thanks. I have never done this before but would like to do this install for myself and not have to hire someone to do it.

I believe everything you're asking about would be answered in this document: https://www.jlwranglerforums.com/forum/attachments/installing-sun-sensor-in-cab-sensor-pdf.298205/
