Where is ignition control module on 1988 dodge van 5.2 v8?

On a 1988 Dodge van with a 5.2L V8, the ignition control module (ICM) is typically located on the distributor. It's not a separate unit like in some later vehicles. You'll find the distributor near the front of the engine, and the ICM will be a small, somewhat rectangular box mounted directly on it.
