    Cylender Head Cover Grounds S52???

    Hey guys,

    I usually take pictures before I take anything apart, but my wife deleated all of the pictures, now I need help with the placement of the grounds on the cylender head. The grounds look like they attach at #1 and #4 coils, but I've read that they go to #1 and #6 coils. It just doesn't make sense though because the stud for #6 isn't a stud but a bolt for the cylender head cover. The stud for the second ground is right by the #4 coil, which I did attach it to. Help!!!

      My S50 has only one on the coil near the firewall.

        The two grounds on my z3m S52 are cylinders #1 and #6. There is a ground from the coil pack wiring harness that is connected between cylinders #2 and #3. Mine looks like the pic below
