Year One has the harness for $519, discount eligible, with a 30% discount. That is about $363. I have found that the price varies wildly on some of the more expensive stuff, so you need to check a bunch of sources. Probably still a lot more than you can do it yourself for, but it does come with a new fuse box which is nice, as water leaking from the windshield wiper grommets usually kills the fuse box.
