You just received your new main board for your hot box and it looks different! No worries, this new board is in fact compatible. The connector location has changed for the two pin ones, and the components are different. Upon reassembly, follow to picture for connector location. Notice the surrounding componets also moved with the connector. (Such as the large blue resistor) One connector has FAN printed on the board. This harness should lead right to the fan. All other connectors plug into the same locations on both boards.
