Here's a picture of the missing gizmo. This is from a 1985 with the 6.9.
This close up pic was taken from a 1996 7.3 powerstroke engine bay. Apparently this mysterious highly confusing strange bizarre wonderful missing mystery gizmo was used to control timing advance from about 1982 to the late 90s. Nobody owns one?
