Wiring Diagram
i am having difficulty wiring my tach to work. i have an analog tach in my old Cuda.(.2005 Vette eng and trans 4 speed auto). i have installed the resistor to add 12v and still not working. tach is good and has been tested. eng and ECM is a 2005 Vette. Also the VSS wiring diagram i have shows the VSS wire green/white from the ECM is C-1 #28. there is no wire there. Another 2005 diagram shows the C-1 #21 pin green/white. it is there. 2005 is an oddball and things are not consistent or not available at all. i have compared to a 2006. they are very different. any help much appreciated. Larry.
