Well, 8 hours later and I have it running.
Get this, it burned the wires all the way back to the fuel pump. It started to melt the plug going into the fuel pump, a few seconds more and I would have been dead.
I had to make an entirely new harness for the charging system, every ground was burned, everywhere. Switches and relays are blown everywhere. I can't get any of my lights to stay on, they flicker on and off. I had to totally reconfigure almost everything. There are so many jumpers in my fuse/relay panel that it's not even funny.
I now have a switch to turn my fuel pump and ECU on. I guess it's kind of cool, I could leave my keys in the truck, but no one would ever figure out how to start it.
