I agree with
Om1kron, go look at how many times people say they regret trying to do the wiring on their own or hacking it up.

If you can get it done for $500 for the whole thing is a great price IMO. If they start to streamline this and put it out on the market I'd go that route.
I would really love to eliminate the wiring mess that is under the hood, and the previous owner did some janky job around the fusebox, ugh.
