Where is the brain box or computer on a 92 dodge 250 van?

The "brain box" or computer on a 1992 Dodge 250 van, more accurately called the Powertrain Control Module (PCM) or Engine Control Module (ECM), is typically located underneath the dash, on the driver's side. However, its exact location can vary slightly depending on the van's options and trim level. It's usually mounted to the firewall or a nearby support bracket.

To be certain, you should:

* Consult your owner's manual: This is the best resource for the precise location of your van's PCM.

* Look for a rectangular black box with numerous connectors: The PCM is usually a fairly substantial-looking electronic module.

* Check online forums or resources specific to 1992 Dodge 250 vans: Searching for "1992 Dodge 250 PCM location" on sites like Dodge forums or automotive repair websites may yield pictures and precise instructions.

Be careful when working near the PCM as it's an important part of your van's operation. Disconnecting it could cause problems.
