Did you have good luck installing the factory hitch?
Yeah, it's not too bad if you have much mechanical experience. The instructions are pretty clear, but there are some things they don't mention. Like how to remove the bumper cover, lol. They show where the bolts are, but don't mention the edges snap in, and where. Some gentle prying with cardboard behind the blade to protect paint will help with that. Also, they include some plastic rivets that hold the bumper cover and wheel well cover together. You need the proper tool for that. I was fortunate that we had one at work. If you can't find/borrow one, you'll have to find an alternative to that.
The worst part was cutting out the bumper cover where the trim piece goes on. They have lines on the inside to show where you need to cut, which is nice. But the plastic is pretty tough to cut. I would recommend cutting in with a drywall razor knife, then using a drywall saw (thin, pointy, jagged kind) to cut just inside your lines. Then use the drywall razor knife to clean up the edges up the line.
I was fortunate that the wiring was already there, with the plug for 7/4 pin adapter right behind the old bumper. If you don't have that, you'll have some wiring to do. I'll try to remember to post some pics later tonight. Took a bunch when I did it, but forgot to put them up.
Finally, I had to have the BCM reprogrammed at the dealer. It's normally $90, but since I had it in for warranty work, and bought it there, they cut it down to $50. Still BS, in my opinion, but better than having to buy an aftermarket harness, and I still have the factory look.
