You have to disengage the PCM (computer) wiring harness from the PCM as the PCM is removed from under the dash. The PCM connector is located on the firewall under the hood to the left of the brake booster, you'll see the a large retangular wiring connector (120 wires) with a single bolt in the middle. Unscrew the bolt, go back under the dash to remove the PCM.

The pcm is located on the drivers side in behind the fuse/relay panel against the fenderwell. You will have to remove the screws holding the fuse/relay panel, and move it out of the way to get to the pcm if you decide to remove it. Make sure to disconnect the negative cable from the battery first before you do any type of work. Also make sure to ground yourself to the van body before you handle it. Without doing this will damage the pcm, (static electricity). hope this will help you.
