2009 Avalanche Suspension Compressor - Dorman # 949 099 - 2nd replacement

Self-help videos aside, am grateful for others doing a reveal. Also when a vendor/manufacturer creates videos to assist customers.
Vague doesn't always help though. This video doesn't reveal beginning to end of R&R for the actual suspension compressor - others have done this.
But none I could tell identify where a separate 3 items attach to and that is a plastic T with (2) plastic lines running to it. As I had removed the prior compressor & had to return it, I didn't snap a photo or write it down which line went where.
This clip shows that T with opaque/black plastic tubing and where it attaches.
