I'm looking at a VAFC, and what I would do would be to get one of those pre-made harnesses (they sell for about $160 I believe). It's about the same price you would pay a shop to splice the wires and that way if you decide to take it off, you can.
I have an extra harness lying around.... I am one of the makers of the harness. You can have it for $140 shipped to your door.
If you were to have a shop do it, it would probably cost around $120 (at least on the west coast). But a shop would splice into your factory wiring harness... VOIDING your warranty. If you get a harness, it takes 10 minutes to install... and UNINSTALL. Very nice.
