Are you saying you have an '04 engine and no harness? If you have an '04 engine then it is most likely TBW. If you want to keep the throttle body (post a pic if you can) you currently have then yes you will need the '04 or newer harness and PCM to run it. TBW truck throttle bodies came in two versions and the connectors are not interchangeable. If you want to run the engine with mechanical throttle then you will need a '99-03 non-traction control harness and also purchase a mechanical truck TB. Depending on your wiring ability, you can make just about any 24X motor run with any GEN3 PCM and harness. If you are changing the accessories to Camaro then forget everything I said above and get a '99-02 camaro harness/PCM and throttle body. Painless harness part number 60508.

From the factory there was a sticker on the back of one of the engine heads with the engine code on it. This engine code can be referenced by any dealership as to what the engine came out of. Not sure why you care what the engine came out of.
