The ECM is located behind the glove box. Remove the glove box door. You'll see the ECM. Disconnect the battery. Remove the three plugs on the bottom of the ECM. There are 4 nuts that hold the ECM in. They are 10mm. Remove them and pull out the ECM. Install is just the reversal. Remember to take your PROM from the old ECM and put it in the new one. New ones don't come with the PROM and it's highly probable that a used one will have the wrong PROM installed as each one is programmed to each specific car.
