@Fless it's an older USB to RS232c from Radio Shack. It's running well on a laptop (Lenovo T510) I picked up from the local value Village for $25. Dropped in an SSD and Windows 7 and It's good to go!
The only "booboo" I just did was to inadvertently downgrade the software on the Tech2 to whatever came on the CD. So the Tech2 is working again but at an older version that doesn't recognize dates newer than 2010. But as long as it knows what my 2006 Subby is, I'll be happy.
Other task is to order in an adapter to allow the wheel controls to talk to my Pioneer 2400NEX
But so far Clock spring installed and working. The one I ordered was missing the connector for Trans temp sensor so.... small loss but I can rewire in later
