Where is the ignition module on a 1994 Dodge Ram?

On a 1994 Dodge Ram, the ignition module isn't a separate easily identifiable component like on some older vehicles. Instead, the ignition control circuitry is integrated into the Powertrain Control Module (PCM), also known as the Engine Control Module (ECM).

You won't find a separate "ignition module" to replace. If you're having ignition problems, the PCM is the likely culprit, along with other potential issues like crankshaft position sensor, camshaft position sensor, coil, or wiring. You'll need a mechanic with diagnostic tools to pinpoint the exact problem.
