To be certain, you should:
* Consult your owner's manual: This is the best resource for the precise location of your vehicle's ECM.
* Look for a large, black, rectangular box with numerous connectors: This is a common characteristic of ECMs.
* Check online forums: Search for your specific year, make, model, and engine type on automotive forums (like Chrysler forums) – someone may have pictures or more specific instructions.
Caution: Always disconnect the negative battery terminal before working near the ECM to prevent damage or injury.
