How do I verify if the Nordyne 664229R is the correct manifold for my furnace model

Resideo SDCR Relay 323613-751 Key Benefits Exceptional Moisture Capacity:The Resideo SDCR Relay is an essential slave damper control relay designed for professional HVAC partitioning where existing zone panel contacts aren't sufficient to handle the total inductive load. This 4PDT relay (4 pole, double throw) lets a single zone output synchronize up to nine dampers, provided the secondary power supply is correctly sized. Built for high density HVAC zoning systems, the SDCR effectively manages multiple damper actuators like
