OEM wiring manufacturing references

I'm about to write a report on automotive wiring, and I'm looking for reference materials for modern OEM wiring techniques and materials (videos, articles, scientific papers, etc.). So if any of you have any good sources in mind, please shoot them here.

Thanks in advance!

Well, this Google search found several SAE papers related to vehicle wiring, whether these techniques are used today is unknown.
