disconnect the battery.
on the two connectors below the ecu ( engine bay, looking from the rear towards the front of the car, firewall left side, metal fins)
feel underneath in the middle of the connector on the bottom most side, there is a nipple that has to be depressed, then the each connectors locking mechanism will slide either to the left or right, depending which side you're pulling off, they'll push themselves off the ecu when you do it right, then just take a 10mm socket and remove the 4 bolts that hold it in place.
i have some pics in the faq on the goth.am link in my sig.
