The Engine Control Module (ECM) on a 2007 Jeep Wrangler is located
under the hood, typically on the passenger side firewall. However, its exact location might vary slightly depending on the engine and options. It's often a black box, sometimes covered by a protective shroud. You'll likely need to look closely around the area of the firewall near the passenger side to find it.
It's advisable to consult your Jeep Wrangler's owner's manual for the precise location or a repair manual specific to your vehicle's year and engine. A diagram would be helpful.
