Did they do the wiring and does it work? I understand you need a special module or wiring harness to hook up the lights. The Curt Hitch from Uhaul woud be fine if I had to use it but I want to secure wiring before I buy the hitch in the case I find someone who will only sell them together. I can't find OEM hitch and harness at any price for the e53.
