You cannot get a "New" engine, however you can get a remanufactured engine. They are available at most parts stores (Special order from their warehouse), or even on eBay sometimes, or you can go the expensive route and get one from a dealership. I have yet to see a "New" Wiring harness either. But replacements are easily found at any salvage yard. There are sites you can visit such as broncoii-ranger.com or therangerstation.com and people sometimes sell their extra parts of their parts cars.
