Maybe someone can help me I have a 2003 Dodge Durango 4.7 2 WD and I'm look for where the computer is located? Can anyone tell me where I can find it and how hard it is to change it out? I like to do all my own work if at all possible. Thank you

pcm is above the front passenger wheel well, it has four electrical plugs facing toward the engine. if you look at your air box, it is just outboard ( towards the outside of the vehicle). is pretty easy to change out. remove the air box, disconnect your battery, unplug it, remove the mounting screws for the pcm, replace PCM, reverse order to reinstall.

 

right about the right rear well... should be a silver box with 4 conections going into it... very easy to DIY

 

Like said above, above the front passenger wheel well, it's a metal silver box with either two or four wire bundles plugging into it. Then there should be 4 or five bolts mounting it to the side wall of the fender. These bolts will be seen looking from the engine to the fender. It's about a five minute job. Take the plugs out, remove the bolts, swap computers, re-plug and bolt, presto!

 

^I'll just repeat the last three guys. It's in the engine bay on the inside fender with a couple plugs. Looks like a silver box with wires going into it.
