The PCM for a van is beside the Brake Booster at about 9 o'clock looking at the booster from the Front of the Van. You may need to remove the Airbox, and push the Hose to the left and disconnect the Oil fill tube from the firewall lip....remove the connector first .....you need a 10mm Deep socket ......for the nuts I used 2 extensions ( about 12 inches total and I prefer 1/4 inch drive)
Then you undo the nuts also 10 mm on each side ..... and the unit slides out like a drawer....careful not to lose the nuts as they are a real Fine thread and hard to find. The PCM code should be on a sticker on it.
