Where is the single wire in-line SPOUT connector on a 1989 Bronco II 2.9 liter fuel injected engine?

There isn't a single, universally located "SPOUT" connector on a 1989 Bronco II 2.9L fuel-injected engine in the way some other vehicles have a dedicated connector for the SPOUT (Spark Output Unit) wire. The 1989 Bronco II's ignition system is controlled differently. The timing control is integrated into the engine control module (ECM) and the signal isn't typically routed through a single, easily identifiable connector labeled "SPOUT."

Instead, the timing signal comes from the crankshaft position sensor (CKP) and camshaft position sensor (CMP) and is interpreted internally by the ECM. There's no single wire acting as a standalone SPOUT connection to adjust timing. You'll find the CKP and CMP sensors themselves, and their wiring, which is what provides the timing information to the ECM. These sensors are usually located on the engine block near the crankshaft and camshaft, respectively. Tracing those wires back to the ECM will lead you to the timing signal's path. Any attempt to find a "SPOUT" connector will likely be fruitless.
