Seems like different part numbers...
I think your part numbers are for the higher spec version.
FYI ECS and DAP Tails are the same setup.
Like I said earlier, upgrading to these should be nothing more than coding and maybe rewiring the channels at the ends. IE no need to take the hatch apart again. I vouch for BEC harness.
I would totally be down to be a guinea pig as I know quite a bit about this, it's just that I literally just bought my car and put the LED Tails on...what a waste :/.
DV52 is great help on here, DMC on VWVortex is also very talented.
I think I am waiting more for some competition on those end adapters. 260 euro or whatever it was is astronomical.
