We’re sorry for the inconvenience. The ADP 767777500 Control Board should have the adapter cable (also called the wiring harness) included. If the product you have was ordered from us, we will need the order number so we can replace it. Please contact one of our knowledgeable customer service representatives @ 435-868-4020 between 8:00 AM to 7:00 PM MT or through e-mail @ email@example.com. If the Control Board isn’t from us, you will need to call the retailer you bought it from or order a new one.
