It looks like the VSS provision that Keisler has on their SS700 trans is for the Ford style analog VSS.
I'm guessing that it will in NO way be compatible with the 12200411 PCM?
If not, I will need to research my options for an in-line VSS with the stock cable-
The problem is that the SS700 doesn't use the threaded GM style speedometer gear adapter (it's just a fitting with an o-ring that is held in place with a clamp like a distributor) so I may need to do some digging...
