I know this has been discussed, but couldn't find it. What is the best company for factory wiring harness?

I used American Autowire bought through RockAuto.com.
Went in very easy. Go to American Autowire website find the part number you need and then check it on RockAuto it's usually less expensive.

I picked up two wiring harness on ebay, and used my melted original one as a template along with a wiring diagram. Turned out nice for way less then a new harness.

M&H. Everything just plugged in and fit perfect. All the wires are factory color coded and tagged.

Thank you very much. My first Olds and don't know a lot about finding parts.

I'm going to go with General Motors.

The fact is that unless there is a fundamental problem with your stock harness (like the car burned to the ground), I find that it's much easier and better to simply repair what's wrong with it.
