2000 k2500 5.7 vortec/5 speed engine harness

[2000obs]

I have a 2000 gmc sierra sl k2500 reg. cab long bed with the 5.7 vortec and nv4500. I was wondering where I could find a engine harness cause mines is all cut up and sensors are missing. It surprisingly runs and drives but it runs like **** cause its missing all those wires and sensors. Would the parts store sell that or would I have to go find a donor truck at the junkyard? And what donor truck would I need?
