Trying to install an electronic cruise control on my 99 miata. Can't locate where the "BLUE" wire from the cruise control unit ties into the appropriate vehicle speed sensor wire. States the speed sensor wire can be found at the vehicle ECM or a convenient location in the engine compartment. Pulled a wiring schematic but greek too me. Anyone help me out here?

Speed Sense	WHITE/ black		instrument cluster or ECM
Notes: The ECM is behind the passenger side of the dash. The VSS wire is in the smallest plug.

The blue wire from the cruise control is for tach and not VSS. The VSS wire should be a WHITE/ purple wire in the middle ECM connector in the drivers kick panel. The grey wire from the cruise is the VSS wire. The tach wire for the car is a GREEN/ orange wire at the diagnostic connector on the drivers fender.

Sorry. I assumed that you are using a Rostra cruise. If you aren't, then the wiring for the vehicle is stil correct.
