They are companys out there that make wiring harness for ls3 motors but they are A LITTLE PRICY. Your best bet is to buy a ls3 computer with the harness it cheaper and it gets the job done. If u have the money spend the 600 dollars on a new harness and get the computer. But if it was me i would buy it brand new and not have to worry bout burning up wires. plus u will get that tucked clean look in the engine bay i hope i helped u in some kind of way..
