[Iljoker4200]

Ok i need sone serious help, been banging my head ont the wall for about 2 weeks now. My fater in law and i are looking for a engine wiring harness for a 99 gmc sierra 4.3 vortec, the problem is finding one at a salvage yard that will work. He thinks 99-06 will work i think 96-99 will work. We are having a problem finding one, so we thought about changing the computer and the harness completely. If someone can help me find what year and make to take the harness off of that will work for my truck or the year and make of a computer that will work. Any help is very appreciated. Thank you in advance.
