Need your opinion - electrical prob

Replace engine in a 2000 V6 Firebird. A wire on the wiring harness was misplace and shorted out a few wires. We replaced the wiring harness and vech will start, however, when starting vech the iginition fuse blows every time. Cant figure out why. Any opinions? Thanks

you still have a short to ground somewhere. i'd start looking for wires too close to the cars exhaust
