93 Grand Cherokee limited electrical gremlin
 

Hello! Another Jeep, another issue haha. 93 GC 4.0. new battery, new belt, new power steering pump, new exhaust manifold, all new ring terminals on the cables going to the battery, unplugged the PCM and then plugged it back in.

When i go to hookup ​the battery it sparks like crazy and the headlights flash and the dome lights come on and the starter turns over and the fuel pump turns on so i quickly unhooked the wires. I unplugged the ignition switch thinking maybe it could have been stuck or bad but that made no difference.

With the keys out and the ignition switch unplugged what would make the entire Jeep turn on??? And how?!
