4. Use the anti-static equipment as detailed on the instructions provided separately.

5. Wire harness connection points on the PCB are marked with a 'J' number such as "J5" or "J8". Label each wire
harness connector with this number to ensure reconnection to the correct point when installing the replace­ment PCB. Connection points are illustrated on the last page of these instructions. The application may not use
all connection points shown in the illustration.

6. Unplug the harnesses from the Main PCB that are easy for you to access. Leave the ones along the bottom for a
little later.

7. Disconnect the hardware fastening the side panel to the control module. Carefully pull the panel away from the
module. Any remaining harnesses connected to the PCB on the inside of the panel will restrict motion. Do not
cause any tension on these wire harnesses.

8. Carefully disconnect any remaining wire harnesses connected to the PCB. The J8 connector for the ribbon cable
includes levers at each end. Move these levers away from the ribbon cable to release the cable from the connec­tor.

9. When all harnesses are disconnected, let the side panel and PCB assembly lie on a flat surface.
