I have a 2004 cavalier and the Pioneer avic-n3 dvd navigation unit.  to hook up the speed pulse signal wire doest it go to the yellow wire coming out of the vss?  I hooked it up to that and the speedo on the nav unit goes up to the max speed without me moving.  so i didnt think that was the right wire.  then i read in the manual you have to drive it to initialize the sensor.  so i was wondering if that was the right wire.  just looking for someone to confirm this or tell me the right wire.  thanks
