Ditching the
7E0 971 095 loom is certainly an option, sadly a costly one as I’m back to square one and having to buy 2 separate cables.
The other side of the 1J0 973 735 connector seems to be
1J0 973 835 and is available online (sample
eBay link )..
I can’t deny, It’s frustrating that VW don’t make that next loom, one to take thefeed from the front sensors (and fogs lights) to the park button, the Park ECU and the light switch etc

. It would’ve be a great part for retrofitters ..
