Look under your passenger side glove compartment - right on the floor where the carpet meets the back of the car. Now look up, the should be a stretch of carpet-like ceiling that can be removed. Remove it. Youll see the bottom of the PCM there, held in place by a white u-clip that is bolted into the firewall area. Underneath that clip on the pcm is a white tear-tag that has you code and your ecm number. This is for 2.5 v6. Cheers
