Hi! Welcome to JustAnswer. I'm Ron Z and I'll be helping you with your question today.

The ECM is located under the hood, driver's side rear corner on the fender apron. Due to the year of the vehicle, the repair manual image is a little blurry, but I can give you what I have here: http://goo.gl/tPdhAp
