It is inside the car to the right of the glove compartment. It's easy to get at, you have to unscrew the black plastic cover that is under the dash on that side. I think i had to remove the glove compartment door, and a couple of light and an airbag connector to get it out. It's about 8"x8"x2" and has 3 connectors color coded red,white and blue. make sure it's bad before you replace it as it's expensive.
Good Luck
