    A noise filter on the ground to the block? Can this be possible?

    Hi guys,

    Hopefully someone would have seen this at some point in time. I have been chasing ground issues for a long time. I finally saw that the one going to the left top side of the block although connected, had the ring bent and broke off when I wiggle it. I figured I would redo the entire ground line and started undoing the harness until I hit something that looked like a lot of wrapped electrical tape but it wasn't. It was hard plastic and I had already cut into it. I have no idea what it is and the electronics seem to sit between the coil ground wires. My harness was made by Painless Performance over 15 years ago. I just called them and they said they did not know what it was.
    My gut tells me it may have been some kind of rudimentary noise suppressor. What I want to know is if it's safe to cut these electronics off and ground directly to the block. Maybe this will get rid of my ground ghosts.
