Part numbers for the headlights...it's tough buying used and trying to make sense of things with Volvo. In my case, I was looking for bendy lights for my S60. There are so many revisions!! I tried to track these for my own purposes, to build a list of "good" part numbers to look fr on EBay. I knew there was a revision around 2020-21 to improve the performance of the lights on the IIHS headlamp rating, as a better score was required for Volvo to make sure their cars remained a "Top Safety Pick" in the IIHS ratings.
I stopped counting and recording headlamp part numbers at 8 different revisions 2019-2022 just for the bendy LED lights (i.e. FULL LED) for a US S/V60. And the problem you have is you don't know what each part number revision represents...is it a major change or just a little tweak, which possibly affects whether you could "mix and match" some of the different revisions. What I ended up doing was going by the mf'd date on the lights, to get something that was comfortably after the IIHS revision, and tried to buy a pair. I'm a cheapskate about it, I will lie in wait on EBay with saved searches, waiting to strike ;-) I did end up getting single lamps from different sellers, but the part numbers match up so I assume they are the same "revision" level (32342532, 32342531)
The HCMs, the modules, that's it's own thing. These are easier though, a much more stable part used across many different headlamps, wit consistent hardware part number stamped on them, so not too hard to buy used and get what you need.
On swapping newer lamps...I am open to help invesitgate a little, find what are the "missing wires" in the lamp plug, see if they could they be added. The way the lamps are integrated into the car, with the HCMs the headlamp still plugs to the car, the HCM is part of the lamp. So there are rather few inputs to the lamp unit, probably just a missing CAN Bus connection is needed for the lamp with HCM, then of course OrBit config to tell the CEM the car has HCM type lamps and that may be all that is needed. It might not be that simple, but it could be...
