When I originally hooked up the 4 wire trailer plug wiring harness to my 2011 Kia Sedona I used the standard 4 wire trailer harness taped into the running lights, directional and ground. When we hooked it up to the Trailer running lights worked, directionals worked but no brake lights. The previous owner told me i need a harness with a converter Went to advanced and bought one with a converter. Okay it worked then the next time i went to use it no running lights but the hazzards worked. Went to use it again and now No lights. A guy at Uhaul told me something about a low volt system on the Vehicle and I would need a converter that you would have to add power to So I bought installed it and it worked Next time as soon as I pluged the trailer in the running lights came on with out the running lights being turned on in the car. Only one directional and no brake lights. Is the tow vehicle damaging these converters ? Anyone had these experiences. Not sure what to do or is there a better place to buy the harness from
Thank you
