I just bought a Navmate 2.0. It needs a car that has a vehicle speed output in the form of a square wave or a sine wave. I want to install it into my 1998 KIA Sportage 4x4 with cruise control. I need to identify this VSS wire, but how? Where is it and what does it look like? Any suggestions? Thinking of it, a wiring diagram for the car would be a big help, too. Thanks.
