OK, thanks. I think I already know what is up. I used the wires coming out of the PCM (which have a "processed signal") to hook to the DRAC. The DRAC is a "processor" which when the truck was stock took the signal from the VSS and processed it for the cruise, speedo, abs etc. I think I need to hook the DRAC to the actual VSS wires coming from the tranny, not the VSS wires coming out of the PCM. Does that sound logical?
