88 Dynasty, no spark

I just got done putting a set of head gaskets into a running 88 dynasty. I get it all back together, and I have no spark now. Looks like I have all the grounds back in place, and everything is plugged in. My ASD relay was buzzing, so I bought a new one, and still nothing. Coil is new too. I noticed some smoke when I first started it behind the alternator, and the ground strap that went from the firewall to the rear support bracket was REALLY hot. I removed the ground strap, and used 10ga copper wire, and moved the ground to the intake manifold, farther from the alternator. I noticed it was bolted to the firewall with another ground line, attached to a little black box with some wires coming out of it. I have no idea what it is, anyone else know? My Haynes manual is useless, all it concentrates on is the 3.3 and 3.8L engines, and LeBaron's.

sounds like you possibly blew a fuse link!!! How many wires are coming out of the box... what colors are they, you're car a 2.5l??
