I have a 100' USB extension cable (Why I have it, who knows! LOL) that I use to run from my computer in the house to my Tech 2 in my truck in the driveway.
After logging into Techline Connect, this is the first screen that I see.

I select my truck under the Recent Vehicles column, and then I see this screen, which shows me modern MDI-based tools, but not the Tech 2:

If clicking on Cancel does not product this screen above, then click on the SPS2 tab at the upper left of the screen.
I click on Manually Select Tool, and I see this screen:

At this point, the Tech 2 needs to be connected to my computer (If I were doing an actual project, I would also have to connect the Tech 2 to the truck at this time). I connect my Tech 2 to my computer, select Tech 2 Legacy Pass-thru and and Reprogram (or Replace and Reprogram, depending on your situation). I click on Next, and I see this screen, where I can see the list of control modules:

At this point, the Tech 2 would need to be connected to the truck to proceed further, as Techline Connect would need to retrieve information from the truck regarding the installed modules and the current version of the software that is installed on each of these modules, so that can know what the current baseline is.
Hopefully, this is helpful to you, James.
