If the furnace has a non-fan controlled board in it, yes. Another way of looking at it is if the furnace has a Time-Delay Relay (2001 and older for all SF model furnaces) then yes, a wiring harness is needed. The part number for the wire harness would be 520832. We do not have this part set up online to order, but you can call in to order. Please call us at 866.332.7881 and any of our sales representatives would be able to assist you in placing that order for the Suburban 520832 wiring harness.
