94 sierra engine wire harness.

hello I just barely make a profile on here, Im new to this. Does any one know where i can get a new or use engine wire harness? story is a person got drunk and cut all the wires under the hood. wires to the engine, and wires that connect to the fire wall, please help. do you guys know of a salavage yard or any place?

A quick google search showed a Pick N Pull in chandler.

I've tried that place already. Someone always gets the vehicle before me. So they would take out the engine and cut all the wires.
