It looks like the seller has a 97.3 rating on ebay. That's not a very good rating for anybody that sells on ebay. That being said it looks like you have enough in that kit to do most, if not all of the job. If replacing original wiring I would take each harness out and unwrap them one at a time and carefully build each new one to match the old. If you do a search there are some threads on here that will walk you through it. Since the kit was so cheap you should have money leftover for the few extra parts you might need.
