Where is the ecm pcm on a 2005 jeep wrangler?

The PCM (Powertrain Control Module) on a 2005 Jeep Wrangler is located under the hood, usually on the passenger side firewall. However, its exact position can vary slightly depending on the engine and options. It's often a relatively large, rectangular black box with numerous connectors. You might need to look closely and possibly move some components out of the way to see it clearly.
