@Savvv here's the link and list of parts from the link, tips I learned, and credit goes to
@TWs/VW for figuring it out from the thread I reference. For those that don't have a pano roof, the thread linked below does contain the proper part number needed. The below is for those with a pano roof.

Parts needed per TWs/VW:
Front lamp assembly with Pano roof Part # 5GM-947-105-A-DYU can be had around $70
VW Repair Wire Part # 000 979 009 E
Butt Connector VW 000 979 941 (accommodates wire range 0.5mm² to 1.00mm²) per TWs/VW
Lockitt POSI-TAP 6 pack wire connectors 20-22 awg per @arkitect06 method
Here is TWs original post from the thread for parts after testing it out:
"...there is an easier, less expensive way to complete the installation with common tools and parts; but, it does involve (1) cutting the Gray 0.5mm² wire exiting Pin 11, Connector T16a (Coupling Point on Roof TH); (2) creating a 3-way Splice using Butt Connector VW 000 979 941 (accommodates wire range 0.5mm² to 1.00mm²), $1.20 each; (3) installing Wire Set VW 000-979-009-E (which I believe is a Micro Quadlok System (MQS) Female/Female), $9.55 each - between Pin 3, Connector T6j (Lamp Assembly WX1) and the newly created 3-way Splice."
I went with
@arkitect06 method of using a Positap to tap into the wire referenced below with the following pics.

*Note - I found it was easier to work from the passenger side to get the installation in place.
Using a trim remover pop off the cover piece, I started from the passenger side and worked my way around. After removal you will see the internals.
Using a trim piece there are four corner tabs to release the internals, again I started from the passenger side and you can slide from the outside portion of the black your trim piece to release the tabs. The next photo I show these 4 tabs.
Per TWs' findings after releasing connectors, popping out the mic and it's joining connector, you want to use the repair wire to tap into Pin 3 into the Lamp Assembly WX1 6 pin connector T6j VW 6Q0 972 706. You will see in the overhead liner on the driver side the Coupling Point on Roof - TH 16 pin connector T16a 8W0 972 416. Now this is where I used the route arkitect06 using a Positap. Take your repair wire and cut in half, strip the end and connect up the Positap. Here is a link to
YouTube on how to connect up the Positab to the exposed wire so you can later tap into the grey wire going into Pin 11 to the Coupling Point on Roof. My struggle was how to open up the 6 pin connector in order to get the repair wire into Pin 3. Here's the trick and thanks to TWs, on one side you see tabs as seen below.

With everything seeming to be a push down and pull with connectors, that's what I was doing with no luck. The top tab as pointed out below you want to slide something like a small flat head or pick tool to lift up so you can slide the parts apart.
End result is the following:

Now on the repair wire the portion that clicks to lock will be upward when inserted and then slide the 6 pin connector pieces back together to lock in place. From here the Positap end that you've connected to the repair wire, you'll want to locate the grey wire going into Pin 11 on the Coupling Point on roof pull back enough to tap into the wire as shown in the video linked to earlier and in arkitect06's pic shown at the beginning for his method I used. After this, connect back up in reverse to make your life easier. Connect your Coupling Point back in the overhead liner, then insert the microphone and it's accompanying piece, connect the controls from the pano (small black connector) and then connect the Lamp Assembly WX1 blue connector. Before installing back in test to confirm buttons are backlit, test controls, and test microphone. Once validated insert the Front Lamp Assembly and you are good to go.
Hope this helps.
