B6 Passat Canbus splice point B415 - B421

[Corners]

I am retrofitting OPS, highline backup camera, RNS510, and the 7w9 bluetooth module and I need to make some can bus connections.

I have been looking for what seems to be the main splice point B415 and B421 but I do not see it. It says in harness but I would think that there would be an obvious point. I have much of the interior out so I can get to most of the dash.

Anyone have a good clue as to where this connection point might be? or even where another good tap point is?

Thanks,
Richard

EDT: I probably should have said this is a 2007 Passat wagon, 3.6 4Motion.

don't bother searching for can bus splice points because they are deep in main harness bundled together and not accessible.
connect at gateway or electronic which is sharing can lines.
