Dell Thunderbolt 3 Card

Hello Dell Support
I need help with Dell Precision Tower 3620
Service Tag: 88xxxL2 Express Service Code: 179xxxxx782 from 2017, no warranty
I need to install a Dell Thunderbolt 3 Card 8DTHW P1XY1 or 555-BEOX.

For this I need the following information:
Pinout motherboard to Thunderbolt header,
In addition signals and power of the GPIO cable,
Pinout Thunderbolt 3 Card GPIO Cable Connector,
In which PCIe slot does the Thunderbolt 3 card go,
Where can I get the driver for Windows 10,

All internet information does not help.

The internet research you did says

For the Precision Tower 3620, the Thunderbolt 2.0 card should be installed in slot 3 for it to function properly.

since you are interested in TB3 card, try the same slot 3.

the TB3 driver for Windows 10 is here (you can search for it in 3620 drivers)
