A few months ago I acquired an’07 Cobalt (vin 1G1AK55F277107005) which had a cracked engine which resulted in the wiring harness being damaged. The car still ran, however. I have been having trouble getting a used replacement engine with the correct wiring harness - after two unsuccessful attempts. The wiring apparently is not interchangeable from one model to another.
What are my options? Can I find out what other models (vin nos.) have the same wiring harness? I haven’t been to find anyone to offer any solutions.
