How do I install a SATA disk drive on my HP Z2 Tower G9 Workstation Desktop?

[jjn5]

I have a HP Z2 Tower G9 Workstation Desktop.
SKU is 4Y0H8AV

This PC is working great. I have a NVMe SSD main drive.

I wanted to add a SATA drive to the PC, so I bought this drive
Seagate BarraCuda 4TB Internal Hard Drive HDD – 3.5 Inch Sata 6 Gb/s: https://www.amazon.com/dp/B07D9C7SQH

I also bought this SATA cable:
SABRENT SATA III (6 Gbit/s) Right Angle Data Cable with Locking Latch https://www.amazon.com/dp/B08FTLXV64


However, I cannot get this to work The PC does not recognize the newly added drive.

I installed the drive into an available drive bay. On the SATA disk, there are two side by side connectors. The PC only has a Connector that can connect to one of them (shown enclosed by the red rectangle below), which I connected.

But the disk also has another connector right next to it (shown enclosed by the yellow rectangle). But there is NO CORRESPONDING connector on the PC side for this one.

How can I install this drive?

Oh, and the other connector cable that I bought, it doesnt help at all. It can connect to the yellow rectangle connector below, but the other end goes nowhere.

Can someone help guide me on how to install this disk into my computer?

Solved it.
Trick is to connect the SABRENT CABLE to this SATA connector on the motherboard:

Found the info from the Maintenance and Service Guide:

Wish HP had had the decency to just have provided this cable built in in their workstation.
