Re: TCC wire with older OD trans

He's saying to have the ground side of the TCC switched through the 4th gear pressure switch and the positive side controlled by the PCM through a brake switch so that it will only lock up in fourth gear and disengage when you hit the brakes. This is how my vacuum setup is wired.

The VSS you chose may not give you the fidelity needed for the PCM to know what speed you're actually traveling. Dakota Digital has a signal multiplier and you may be able to change the input via tuning software to remedy this.

I think this is very do-able and a neat option to have if you can get it to work.
