10. The new ICM does not have a 240-spade terminal; this connection is now in the middle of the Molex connector. The wire adapter has a cable coming out of the Molex that needs to be connected to the 240 gray cable as show in Fig. 11.
11. Connect the yellow/white wire coming from GND in the ICM to the GND cable as shown in Fig. 12.
12. Connect the red/yellow wire coming out of the multi-pin connector to the red/yellow wire coming from the PCBA as shown in Fig. 13.
13. Connect the yellow wire labeled 24V from the multi-pin connector to the yellow wire labeled 24V coming from the PCBA as shown in Fig. 14.
14. Reassemble the heater control panel assembly. Be sure that the control panel can be adjusted without having to lean over the exhaust vent.
15. Connect the Orange/yellow wire labeled IND to the Orange/yellow wire labeled IND that comes from the PCBA as shown in Fig. 15.
16. Connect the Blue/Yellow wire labeled TH to the Blue/Yellow wire labeled TH that comes from the PCBA as shown in Fig. 16.
