You need to find the wiring schematic on the furnace, possibly on the back of the blower cover or furnace cover.
You have 2 connections to determine. First is simple the motor connection. The 2nd connection is the high limit safety and I do not know how your old furnace fan control handles that. I see 2 wires from your photo going behind the control box. The Honeywell control has many ways to wire their control once you know how your old control handles high limit safety.
