Anyone know the difference between stranded THHN (I think that was the letter combination) and primary wire? I bought primary wire for my harness because it said it was for automotive use. The THHN wire said it was also oil and fuel resistant. Just wondering the difference. The THHN was slightly cheaper than the primary wire.
