    Tach fluter

    I am doing a late model S52 OBD2 swap and finally go the correct wires spliced (#20and#9) to make the tach work. As soon as i connected the wires the tach fluttered a little then stopped again and never came back up. Has anyone experienced this?

      I thought that but wouldnt it still work with the wrong plug and just not read the correct RPM?
