The 628661 uses different connectors than the older 621271 board on your 1200. Norcold used to include adapter harnesses (pigtails) in a board kit for this swap, but those kits have been discontinued, and we don't have the adapters to sell separately. The easiest fix is a board that plugs directly into your existing wiring: the OEM 621271001 or the Dinosaur 6212XX. Both are in stock. Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you.
