i am not having any luck location the ecu for the engine,although i have found the antilock computer and about three others anyone know where the main computer is?

should be above the break pedal. If not there it's in the passenger side kick panel.

Open the hood and look between the brake booster and the fender. There should be a large plug with a bolt in the center. This is the harness that connects to the processor. Inside you access it by removing the lower dash panel (by fuse panel and is black). You can see the processor between the brake pedal bracket and the emergency brake assembly. It may be held in place by a white plastic clip (I can't remember, it's been years). You may need to remove the knee panel under the steering column to access the processor. Hope this helps.
