Help with Twisted Pair from OnStar

I'm currently in the process of thinning the body harness. I've been doing good until 16:00 into the video Part 10. It says to keep one pair of the twisted wires from the OnStar at the Black and Purple Multi-plug. My twisted pair goes to the anti-lock brake connector. It looks like from there goes to other connectors and then possibly down to the Black and Purple Multi-plug. I mistakenly cut it at the anti-lock brake connector, but kept the wires.

There is nothing said about the anti-lock brake module and connectors. I don't plan to keep them, what should I do with it? Will it cause an issue if it's removed?

The data wires daisy chain from front to back.

You will break this connection when you remove the onstar and/or the ABS connectors.

Make sure that they are reconnected from the BCM to the ECM.

So it's okay to completely remove all the wires to the ABS as long as I bypass it with the data wires?

I removed the ABS plug. I will need to solder the twisted pair of wires that went from the ABS to the ECM to the Blue/Black multi-plug of the BCM. But I have found two sets of what look like brown and brown/black on the plug. I'm not sure which set to solder to.
