I need a wiring harness for my 99 convertible z28 m6. I have wires that are loose and exposed/damaged on the PCM as well as many other issues. I'm sick of my random no starts and this is the third tow bill.. I've spent like 225 on towing alone plus like 300 for some jackass to track down a "loose ground" that I don't believe is even the issue because the no starts are still occurring. Just because when it left his shop it started consistently doesn't mean he fixed the problem. I'm hurting for $ but I need a new harness so please go easy.
