Years ago I bought a book at NAPA that had all the engine wiring diagrams for most all vehicles. I haven't looked to see if they have a newer edition that covers the newer year vehicles. It might be worth a look. There is also a wiring conversion book on ebay. I haven't bought it, but I thought I'd mention it so you can check it out if you like.
