I have a 1994 Toyota Celica that I recently needed to jumpstart. However, I made a mistake and accidentally switched the jumper cables. They weren't on for long, but I think the damage was done as I can't get the car to start. However, I think something is wrong with the electrical system. What else might I have fried? Before I connected the batteries, my power locks worked fine, afterwards I couldn't even lock the doors or get something as small as the clock to turn on. The fuses all appear intact, so what else may be wrong?

No, however I did notice that the open door symbol on my instrument panel does light up. That was the only evidence of electrical activity I could see. The radio doesn't work, the clock doesn't work, the chime doesn't work, the locks don't work, and the windows don't work. And the car definitely won't start.

I am not 100% on this but I think you fried your ECU. You may replace it, just to find you still of some problems, in which case I would think the BCM shorted to. I am sorry I couldn't help you more and I hope someone else will chime in
