Ouch, hopefully you didn't smoke the PCM. Here is the starting wiring diagram.

Focus on the fusible link on the lower right of the diagram.

PCM is Power control module aka computer.

The fusible link is something like a breaker on a house, it will default before trouble happens down the line.

Not sure on this one, but fusible link may look like normal wire.

Check for continuity between the two ends of it.
My guess is that it fried the link.
