Where is the ignition control module located on a 90 dodge ram 150 van with 318 Does it even have one?

The 1990 Dodge Ram 150 van with a 318 engine does not have a separate ignition control module (ICM) in the traditional sense like some earlier vehicles. The ignition control function is integrated into the engine control module (ECM) or Powertrain Control Module (PCM).

Therefore, you won't find a standalone ICM box. The PCM is usually located under the dash or in the engine compartment, often near the firewall. Consulting a wiring diagram or repair manual specific to your year and model will help pinpoint its exact location.
