Where do you find ignition module on 1996 dodge Ram d50 mini pickup?

The 1996 Dodge Ram 50 uses a distributor, not an ignition module as a separate component like some later vehicles. The ignition control module is integrated *within* the distributor itself. Therefore, you won't find a separate ignition module box.

To find it, locate the distributor; it's on the engine, usually near the center, and has a cap on top with wires going to it. The entire distributor assembly contains the ignition control module. If you need to replace it, you'll likely replace the whole distributor.
