I just screwed up my electrical system bad. I was installing a CD player and somehow when i plugged in the harness, it sparked, all interior lighting went out, and then there was a bad burning smell coming from the right side. So far all fuses checked in the fuse block and power distribution center seem all right. Nothing works, but the headlamps, dash gauges, and the ABS light and check engine light in the dash. The fuel pump doesnt work, dome lamps dont work, radio, wiper, seats, just about everything else. This all resulted from a radio being plugged in improperly, so my question is what happened and how do i fix it. I need my jeep working tomorrow for work at 9, so any fast help is appreciated. Its a 93 Jeep grand cherokee with the 4.0 if it matters.

Welcome to my world, not a single damned electrical component runs.

Start looking for fusable links. Last time I had a massive electrical failure, I had one of those go out on me. I only assume that the "wire" type fusible links are still used on 93 Grands.
