I have a 1997 f150 4.6 Windsor. I am trying to remove the passenger side valve cover. I have a Haynes manual and have looked on line to determine if there is a connection on the back of the valve cover that will not allow you to remove it. I have looked at a 303-01B: Engine — 4.6L and 5.4L document and cannot find a reference to a wiring harness or bolt that attaches to the rear of the valve cover. So is there a connection of some sort that on the back of the wiring harness. Thanks
