* Engine: The PCM will vary depending on whether it had the 305 cubic inch (5.0L) small-block V8 or the optional Tuned Port Injection (TPI) 305. The TPI system used a more sophisticated PCM.
* Transmission: Automatic or manual transmissions have different PCMs.
* Options: Features like air conditioning, cruise control, and various electrical systems could affect the PCM's programming and possibly some auxiliary control modules.
To find the correct PCM, you need to look at the part number stamped on the module itself. This number is crucial for ordering the correct replacement. It's usually located on a sticker or stamped directly onto the PCM's casing.
You can then:
* Use the part number to search online retailers or auto parts stores.
* Consult a GM parts catalog using your VIN. This is the most accurate way to determine the correct part. A GM dealer can access this information.
* Check a reputable online Camaro parts supplier, providing your VIN or engine details.
Without knowing the engine details and the part number from your existing PCM, it's impossible to provide the exact correct replacement.
