Need help from the wiring experts on coil pack terminal connector

On the large connector that screws onto the coil pack module is a terminal marked J, the diagram I have shows it as "Fuel Injector timing input". Can someone explain what this does and where does that signal or wire come from? The reason for the question is I am dealing with an old DFI accel system and there is no wire going into this terminal on the coil pack and I am wondering if I need it. My 86 has this wire going somewhere but this engine I am working on does not. This is on a stand and just trying to get this engine running. Thanks for the help.
