This is a guess, but it isn't a wild guess. The TAA signal is probably a digital signal, with a variable frequency wrt speed.

In the case of the BMW motos, it is a 'manufactured' signal based on a the sinusoidal signal from Variable Reluctance wheel speed sensor.

Some automobiles use the term VSS to describe the signal from the pickup on the transmission output shaft.

With a couple of different checks with a good digital meter you can probably get a good enough 'picture' of the signal to know if it will work with the cruise control.
