Problem with the electrical system Swift 1.0 mod 96

Hi, can anyone help me? I was doing maintenance on the instrument panel. I took everything apart, removed the steering wheel, the turn signal lever... and reconnected everything in its proper place! But when I try to start the car, it won't start, the radio doesn't work, the power windows won't go up, I checked all the wiring and everything seems to be in order! I would really appreciate any help!
