2000 Ford Taurus Many power features all died at once

After about 3 months of having my aftermarket stereo work perfectly, i pulled it out again to better tie down the excess wiring. Once it was all back in place, the stereo was not receiving any power, the power locks and windows didnt work, the interior dome light wouldnt light up and the speedometer and odometer stopped working. I double checked to make sure all the wiring was intact and the same as before but nothing seems to work.
