The VSS in 123's sends around 8,000 ppm. In my car, the signal came to pin 11 on the factory cruise amp (I think it was a green wire). The cruise amps in 123's did change at least once though, so yours may be different. Check a wiring diagram.


(The first post on the third page of this thread contains my instructions for wiring up the factory control stalk.)
