I have a hitch on my 2005 X5 but no wiring harness. I use it to haul tailgate supplies and bokes on a homemade rack. Now I have urgent need to pull trailer during the day and dealer has no stock of harness. Has anyone ever used tail lights as temporary wiring to meet minimum requirements for a day or two? Any ideas appreciated. I know uhaul has bulbs with auxillary wires attached but don't know what car would "think" about that added resistance.
Thoughts anyone?
