What is an incline spout connection. Its supposed to have something to do with the timing on a 1989 ford Ranger xlt ,2.8 dual 4 Cycinder extended cab

The "Inline Spout Connector" is used to control the engine timing by dis-connecting the timing control from the timing control unit, and you must remove the inline spout connector before you can change or set the ignition timing, and if the inline spout connector is missing, then the engine timing will not be controlled by the dura-spark control unit, the check engine light should be on, and the engine will perform poorly. Usually it is located out by the distributor or over by the dura spark control unit.

It is normally a small squared looking grey plastic thing that should be in the end of a wire connector, and that is the only thing that will on the end of that wire connector, and it is basically just a jumper plug. Here is a similar image of what you should be looking for.
