and all dummy lights come on with the key turned to run. they go off after its running.

you should have enough room to jump the starter with a screw driver or the dip stick even. if it cranks and runs via jumping the starter at least its drive able.

dont have a clue as to why this would happen by cutting abs wires and replacing the harness, the car was off, theres no power to it when keyed off. should have been ok.
