Model: 5C3Z-12B637-BA
Great warranty and total satisifaction guarantee stated in description but Amazon has no contact info for either seller or Manufacturer. Nothing found on web it’s just a big run around. I’ve suffered a financial loss in excess of $2000.00 directly because of this harness. I want compensation for my loss and a full refund but all I get is the runaround to contact through Amazon and no info available. I’m disgusted with the whole process of smoke and mirrors. ... show more
