Hey, I ordered the DDM 6000k kit for my tahoe, and when I got it, it only had the ballast and bulbs. I feel like an idiot, but it says at the top of the page that the wiring harnest is sold seperately, was I suppose to buy the wiring harnest at the bottom of the page for 20 bucks? Could you please tell me, I didn't want to start a thread on a simple question and I saw that you actually live in driving distance from the company. Thank you.
